Gulf of Mexico Biotope Plans

Hello everybody

Introduction
My 90g reef aquarium has been setup about a year now. The tank is stocked with 3” of mixed sand and rubble (180-190 poundish), 50 pounds of Florida aquacultured rock, 70 pounds of Haitian Lettuce Coral Rock and another 15 pounds of the Haitian Lettuce Coral Nano Rock. Haitian rock was acquired from eTropicals.

The rock was aquascaped in a large collection on the right hand side to form a large hollow cave opening and stacked around to create multiple openings in the front, sides and back.

A detritiovre kit from Inland aquatics, a coral banded shrimp, a few hermit crabs (because I like them) and a dozen extra snails were added. The tank is well populated with bristle and spaghetti worms and has a dozen or so feather duster worms.

Originally, the tank was planned and partly established as a Caribbean rubble zone biotope. Having been aquascaped for about a year, I have changed my mind and not doing much else with it. I have just started stocking corals in the last few months so I have been stocking according to my next plan. Also, there are no fish in the aquarium.

For those who were involved and helped me setup my first plans, there was a lot of back and forth and uncertainty. There was also some good advise that I looked past and it all has started making me rethink the plan now that I am ready to drop some $$$ into stocking.

The display tank is a 90g AGA with a 30g sump. The tank is lit with 2-150w DE bulbs and 2-110w actinics. The tank is circulated with 2-Tunze Stream 6060’s and the sump is circulated with a Mag 7. Tank has a 1/4hp chiller to maintain 75-79 (I live in New Orleans and I set my A/C back as the chiller is cheaper to operate). Skimmer is a Euroreef CS-8.



My New Plan
The new plan goes back to my original idea, which was a Gulf of Mexico patch reef biotope. The planning would be based on the Flower Gardens Sanctuary. NOAA has recently put together an excellent encyclopedia of marine life and I have used and their image library this to help me with my plans.

Basically, the tank layout would work like this:
Substrate
1-All the corals and inverts would be moved to ‘temporary quarters’ for a weekend out.
2-All the rock and half to three quarters of the sand would be removed and resorted.
3-A 1-2” layer of sand (about half) would remain in tank as ‘undisturbed’ as the ‘base’.
4-The dense aquacultured (50 pounds) rock and some of the heavier Haitian Rock (20 pounds) would be laid flat to create a raised hard bottom, covering about half the tanks footprint. The hard bottom would focus on the right, leaving the left mostly open. Extra pieces would be placed in the far rear of the left just for background.
5-The remaining sand (about the other half) would be added back to stabilize the hardbottom
6-The large pieces of the Haitian rock would placed on top the right hard bottom in groupings of pillar formations. A few of the ‘pillars’ would be capped with the large flat pieces. I might even get creative and try to recreate some of the lettuce formations at the base with some curved pieces. I will only use about half the Haitian rock to reduce the rockiness and open up some more water.
7-Smaller pieces of the Haitain rock would be epoxy’d around the sides to give some texture to the structure. Again, I will only use about half the smaller Haitian rock to reduce the rockiness and open up some more water.

Stocking Inverts
1-My White Claw-Orange hermit crabs would be returned to the tank. The scarlets and blue legs brought to the LFS for credit.
2-Snails would be returned as all reproduce within the tank. I may add another half dozen ceriths however.
3-Coral banded shrimp remains
4-Two Gorilla Crabs will be hunted while the rock is removed. Fate to be determined.

Stocking Corals
My goal here is to dominate the tank with one coral species and dot the tank with a few others. Atlantic hard corals are not collectable so a few Pacific recruits have been acquired and/or identified as fill-ins.
1-Polyps will remain in QT and sold to other hobbyists or the LFS.
2-3 of the 5 Monastrea’s will be restocked into the display. The other 2 will be traded at the LFS or sold.
3-The ‘Ice Blue Monastrea’ (as known until further id’d) will dominate the display. I have so far acquired 11 frags from the same mother colony. This would be used to substitute for one of the ‘great star coral’ Montastrea sps and I am looking for this to be about half the coral coverage.
4-My red-brown and dark green single specimens (also require better id) will placed at or near the bottom of the hard structure. I may frag the red one to scatter it in a few months if I see some growth.
5-Encrusting Porites will be used randomly through the display and account for about ¼ of the coral coverage.
6-A single Scolymia or a singe Lobophyllia (in place of Mussa) may be placed in the display.
7-I have a single gorgonian that was my first coral in this tank and has done exceptionally well. I may keep it in this tank despite there rare or near non-existence in the Flower Gardens. I am thinking dead centered in the open swim area of the tank, right in the currents, base partially buried.

Stocking Fish
My main goal on the fish is to have a relatively low fish bio-load compared to the corals/inverts. I have come to a choice of 3 options:
A) A single Bluehead Wrasse and Three Blue Chromis
B) Five Blue Chromis
C) Three Blue Chromis and 2 Neon Gobies

My concerns are that the Bluehead Wrasse will eat my shrimp and hermit crabs. If he grabs a hermit once and a while, I would not be too worried. But if he is going to just decimate their existence or take my coral banded shrimp, then I am a little concerned. I am also concerned about the very short life spans of the neon gobies.



Final Thoughts
I will dewater the tank as low as I can to limit how much water gets murked up and keep as much of the current water as I can to limit initial stress. But I will be picking two 50-gal garbage cans so that I can perform some bi-daily 25% water changes for a week as I will be stirring up some anoxic areas of the sand bed and probably reducing the nitrification capabilities for a few weeks. I will wean down to 10gal for a couple weeks and then finally 5-gal weekly water changes, which is what I do now.

So what are your thoughts on the plan. Any concerns or suggestions?

Thanks,
Chris

Sounds like nice well thought out plan, i look forward to seeing it's progress, and pictures of course.
 
Status Update...

Status Update...

This past weekend, I broke down my aquascaping and redid the tank to be more 'brain and bolder coral friendly' as opposed to the old rubble zone.

On a sad note...
During the move, I have suffered to casulties.

A plexaura gorgonia that has been with me since the beginning as shed most of its tissue from the axial core. I am not removing it yet as I have a glimmer of hope that some tissue will remain and it will recover, but it is not likely. This was my first coral and was the only of three to survive shipping, the other two failed to make transport and the vendor refunded me for the other two. This one had grown just short of an inch, sprouted three new branches and encrusted the epoxy and base rock. I was careful not to expose it to air and was very sensitive to acclimation as it was moved from and back to the tank. This is very sad for me.

Another loss was an unidentified Montastrea head. I just recently acquired it and is was one of the ones that fully opened at feeding. I was quite suprise by its demise. I have to admit, I was thinking about trading it to my LFS for some Porites he has been trying to acquire for me. It is still sad that I lost another life, but I had no attachment to it like the gorgonia.

My other Montastrea and Porties appear fine so far. Remaining I have 5 Porties sps. frags, 11 Blue Montastrea sps. frags, a Red-Brown Montastrea sp. head and a Neon Green Montastrea sp. head. The porites are opening to light and half the Montastrea is 'responding' either my extending tentacles or my inflating. A couple of the frags are not responding but do not have any rapid recession like the one above.

New Aquascaping
As far as the aquascaping goes, I am very pleased. I went from a tank of a rubble wall with a large cave to four distinct 'pillars'. What I wanted to accomplish was two large mounds and two smaller mounds of what would look like old boulder coral growth. however, I had 70 pounds of lettuc coral rock to incorporate so I what looks like a mix of old boulder and plating coral growth. Also, about 25 pounds of rock was not replaced back into the tank. About 20 pounds was donated to a friends new tank to help seed it. Another 5 pounds, along with a lot of rubble is being preserved in a bucket with a Maxi-jet waiting on my new fuge to come it.

New Fuge 6g Coming
I have ordered a CPR hang-on fuge and should come in on Friday. I am going to add the remiaing rubble and 5 pounds of rock to it. I will also add a few pounds of new 'live sand' to help reintroduce any new life that may have been lost over the last year and help keep things diversified. I am not into the magic mud.

I went with the hang-on fuge because it gave me more capacity than anything I could have worked into my sump. Also I like the free fall of pods instead of them being pumped in. It may not make a difference in the end but I still like it better.

New Sand Storms
One disadvantage to removing the rubble is my Tunze streams now blow sand everywhere. I like what it has done to the sand bed with new dunes in the back and between the pillars, I may leave it. However the sedimentation on my corals is going to be a problem. I will order some magnet holders and blow them lenghtwise across the top of the tank instead of from the rear corners to the middle of the front glass. If it is still a problem, I will drop back to two streams instead of three. I really want to have high flow 'above the reef' for my Porties and Chromis with the pillars providing some flow shelter to the Montastrea heads.

Pictures will be posted tonight.

Sounds like a great plan to me.
Fish options:

How about a cherub angelfish in place of the wrasse? Also, yellowhead or dusky jawfish could be good options too, either with or without the gobies.

At first I thought of the swissguard basslet or a royal gramma in place of the wrasse, but they may be just as tough on the shrimp, so no go there. Same would hold true with blennies or hawkfish.

Pipefish are pretty tame, would go well with the gobies too.


I had posted my dream tank of a "Floribbean" biotope, mostly LR and any inverts that survive. I'm planning, and this is a year or so away, a 300 g or so tank with a queen angelfish as the centerpiece fish, perhaps a blue tang, the swissguard, bluehead wrasses and blue chromis, etc. I'm working on the logistics and infrastructure and will have it going soon. I'll be keeping an eye on this thread though. The tank that I'm having made now is a local biotope for me, an "oyster" reef blenny tank. The guy building it for me is almost done (100g cube with a 40g sump) and should deliver any day now. Once this tank is up and running then I'll begin the Floribbean project.

Good luck with your gorgonian! Hope it survives!!!!
 
Hypsoblennius You and I are on the same page buddy. My long term plan is to grow this tank out to fill in a larger tank when I build a new house in a few years. Funny about your fish recommendations, My original plan from a year ago was a Carribean Rubble Zone Biotope featuring a mated pair of Cherubfish as the centerpiece fish. Before that it was a harem of Royal Gramma. Companion fish was going to be the Redlip Blenny. Corals were going to be polyps, gorgonia's, ricordias and a single LPS. Pretty much all the generic stereotype corals for a Floribean display.

Then one day I was checking out the Flower Garden Sanctuary website and came with an entirely different idea. Since I did not have any fish and few corals, the transition was easy.

Also, i did consider the swissguard basslet for this display and counted it out as I wanted the gobies instead. I wanted to limit the fish to two species to keep the display simple and not too busy. Very much how I will have 30-35 corals but they will all be one of 7 specimen, including 11 frags (and hopefully 15-20 frags) from one mother colony of an Ice Blue Montastrea.

Good Luck with yours.

Now for some pictures...

The Old Aquascape
Below is the old Rubble Zone Aquascaping. The scape work is made up of 50 pounds of Florida Aquaculture Rock and 85 pounds of Haitian Lettuce Coral Rock.

Here are most of the inverts removed from the tank prior/during the dismantling. They included a Golden Coral Banded Shrimp, Orange-White Claw, Scarlet Reef and Blue Leg Hermit Crabs, Cerith Snails and a Pencil Urchin. The shrimp, the Orange Hermit Crabs and the Cerith Snails were retained for the new tank setup. The other hermits donated to a friend. The Urchin and a Gorilla Crab were brought to my LFS for credit. Also not pictured is a Caribbean Pistol Shrimp; it was kept for the new display.

This is the last picture of my gorgonia before its death.

The New Aquascape
Below is the new Patch Reef Aquascaping. The scape work is based on the same 50 pounds of the dense Florida rock serving as the base for 2 large mounds. Another 50 pounds of the Lettuce Coral Rock was used to create the two small mounds and to create some plate and old lettuce coral growth on the two larger mounds. About 5-10 pounds of the smaller lettuce coral rock was placed throughout for some texture.
108047DSC01172.jpg


The large right mound structure:
108047DSC01173.jpg


The moderate middle mound structure:
108047DSC01178.jpg


The two small mounds on the left side of the tank:
108047DSC01179.jpg


The new aquascaping feature plenty of open swimming space at the top half of the tank and on the left side of the tank behind the foreground pillar. The two large mound structures shelter strong flow from the Tunze Streams providing shelter for fish in the valley. These two structures also provide plenty of mounting space for the encrusting and boulder corals I plan to have.

Two of my Tunze have been remounted using the magnet holders and has made a great improvement in my flow pattern. Tomorrow, I will post some pictures of the tank with some coral placements.

I still owe some latest pictures with the corals replaced. We lost cable in a near miss with a large storm last night.

But the gorgonia fully degraded and only the skeleton remains. I had hope that the base would atleast hold and regrow but that did not even happen.

Six of my eleven Ice Blue Montastrea Frags are at least partially opening at night; two are fully opening. The other five are not opening but instead are inflating. Also my Red Montastrea inflates but does not open.

Pictures tonight.

I love your aquascaping, very nice!!!!!!!

I would love to try gorgonions and SPS...I might give the Pacific SPS a shot and see how it goes. I have a feeling the queen angel will make short work of them, especially the Gorgonians and any sponges that I add. So, I got to thinking, perhaps a "split" tank, with live rock being the divider (perhaps DIY LR with an egg crate built in barrier, about 300g FOWLR and any inverts that survive under the rule of the queen on one side, and a "reef" on the other side, kind of like a fuge of sorts, with the only fish on that side being small non-coral eaters. That way, perhaps tunicates, sponges, gorgonians and the like might have a chance, maybe even a deep sand bed on that side with a jawfish colony. I have the space to do this...

...I'm thinking of having a tank built, 96X48X24, about 479g. The domain of the queen could be 72X48X24, about 359g, and the "reefuge" would be 24X48X24 or about 120g. That's the dream to date. That way I could get the best of both worlds. Were you happy with your source for the live rock? Would you go with them again?
 
Hypsoblennius I actually thought about that once. My idea was a tall tank with it split horizontally. The idea was an elevated sand bed with rock work, but in the center of the tank would be a large cave shaft to a lower hollow cavity that would be partially cryptic but viewable.

I got the Haitian Lettuce Coral rock from www.eTropicals.com. It was not high quality at all and took a long time to cycle, but for the shapes, it was worth it. I got the Florida aquaculture rock from my LFS and I am not sure where he gets in from. I believe there are only about 6 sources though and it is pretty much all the same. It was a good mix and I would do it again. In fact I will. In a few years when we build a house, I intend to incorporate this tank into a 300 gallon and will purchase more of the same rock.
