Caribbean Biotope Seagrass Tank

It's amazing how nature bounces back.

Yes, it is!!! How is the ulva holding up?

Chasmodes bosquianus is the striped blenny, found along the Atlantic coast from NY to Central Florida. It has two very closely related cousins, C. subburae (the Florida blenny), ranges from the Central Atlantic Coast of Florida around to the Gulf Coast of Florida, and C. Longimaxilla (the stretch jaw blenny) that ranges from the Central Florida Gulf Coast to the Texas Gulf Coast. Their ranges overlap a little I think. There is another blenny common to the Chesapeake, Hypsoblennius hentz, the feather blenny, that ranges to Florida as well. I would keep one of them too if I am lucky enough to catch one.
 
The ulva is getting brittle and breaking into smaller pieces, but does appear to be growing as well. I think it will hang in there until hypo is over then it should come back a bit. There are pieces of it all over the tank now. I'll probably do a little straightening today, so it's not quite so ugly. I'm still mortified from yesterday…

I love the idea of a blenny community tank. Hopefully you can catch multiples of each, to get that natural, social behavior aspect going. They are such cool fish to watch!

I guess that's a slight downside of catching your own. You can't just click 3, like you can at an online store. I imagine that complicates the order of introduction process as well. I'm sure you'll work it out.
 
What determines whether or not you can keep multiple blennies in a tank?
Some species won't even tolerate one other blenny in the same tank; like a bi-color with a tailspot.
 
I'm no expert but I think herbivorus blennies are more territorial and carnivorus ones are more gregarious, as a general rule. Obviously you'd want to research candidates for doing more than one. The two I've researched-barnacle blennies and sailfin blennies prefer to be sociable. It seems like larger ones are less sociable and smaller, more.

Chasmodes, you want to weigh in here?
 
I think you may be right Michael. Both the striped and feather blennies are omnivores, so food competition may be less. With striped blennies, competition is for suitable empty oyster shells for breeding spots. I read on an oyster reef they may be as close as 5" apart!

It depends on the species. As long as there are plenty of hiding spots in a big enough tank, you can keep multiple C. bosquianus. I've seen a few tanks that have kept multiple striped blennies and read about others too.

I think H. hentz tolerate each other a little less than C. bosquianus but I doubt anyone has reported trying it. They also live in an oyster reef environment, so maybe? My question is if both species tolerate each other? Maybe we will find out!

Interesting stuff..

Blennies are a favorite of mine due to their stupid looking heads and great personality. Lol

One of the coolest things I remember from snorkeling in Curacao were the little blennies that resided in holes in the big yellow brain coral colonies. Popping in and out.
 
That sounds fun. I'd never leave the water!



It sure was! A jellyfish sting and crashing a moped couldn't keep me out of the water. Lol
I've got lots of pics and videos of the snorkeling in Curaçao in my build thread if interested.

Try to poach you away from Michael. :P
Or at least derail the thread :P

Your oyster reef tank seems like a cool idea.
Where does one primarily hunt for the blennies? How far inland?
How do you plan on collecting them? Slurp gun, dip net, barrier net?
Blennies are a tough one to collect!
 
Derail all you like! Fun discussion.

After a little straightening. Not much red to be seen but I do have some frags hanging on.

Molly fry cruising over the newly pruned grasses. I seem to have more shoal grass than manatee grass lately. I think it dealt with hypo the best.

I do like the ulva.

Almost there! Just hold it together for a few more days…
 
Thanks Michael. I will derail a tad, but carry it over to Sam's thread after this post. Your tank is still beautiful, like a winter forest right before spring, and spring is only a couple days away. Life is there, it just is waiting for the right conditions.

I admit that I haven't been on your thread in a while, but was watching it during your initial build stages. Wow, that rock wall turned out great! It was beautiful work before, but the way life abounds on it is amazing. I'll have to go back to where I last left off and catch up to see your pics. I see you're a Toyota man... FJ Cruiser Trail Teams addition here :bounce2: Nice work on those lights!

Blennies are a tough one to collect!

Thanks, I hope it turns out as planned. The two blennies near me are found in the Chesapeake Bay and the saltier areas of the brackish tributaries. They prefer oyster reefs, but will hang out along any structures close to shore in the shallows during warm months, out deeper during cold months. You can catch them along undercut banks along shoreline reeds near beaches, around jetties, pilings, rip rap or piers. I live about an hour to an hour and a half from my closest collecting spots.

I have collected species other than blennies in a seine, but all of the blennies that I've caught so far have been with dip nets or aquarium nets. I'm not sure how much that I'll collect along oyster bars because they are really hard on equipment, razor sharp. For me to successfully collect in those areas, I'll need to use traps.

I've made traps our of milk crate style boxes that are weighted and contain faux oyster cultches or bottles, hiding spots for blennies, skilletfish and gobies. You simply pick up the trap (or haul it up with a rope) and the fish scoot to their hiding spots. Most of the time they stay in them when you pull the box out of the water. It is wise to have someone follow behind with a dipnet if you have company to help, especially getting the net under the box as it leaves the water.

I have yet to try a snorkeling using a slurp gun or a net. Visibility isn't all that great in the Bay and jellyfish during warmer months become a bit of a nuisance.

Another way to catch them is by microfishing with hook and line. I haven't done it, but I've seen others do it.

It's funny, Chasmodes, I was thinking the same thing about my tank. It still has some beauty, and more to come, like the wildflowers in the spring. I just hope I am able to steer it in the slightly different direction I have planned, and this new direction looks and functions as well too.
 
Michael,
What salinity are you planning on bringing your tank back too? If the green macro died back at hypo. but the reds hung on, maybe something in the range of .016 or .017 may be perfect for you. I was talking with the LFS employee the other day and he said their wholesaler is now sending stock at .016, and therefore they are keeping their tanks the same. Is there any reason to go higher than this except for certain corals?? Your thoughts??
 
You are definitely onto something, rucnnefish!

Many of us could do well to reduce salinity to below natural seawater levels. It reduces fish's efforts to osmoregulate. So it's one thing we can do to make their lives just a little easier. I don't know how well corals handle it though. My condylactis anemone and the hitchhiker corals on my live rock don't seem to mind.

I run my tank at 25ppt, or 1.018, approximately. This is manatee grass' preferred salinity.

For hypo, I've been running 13ppt or 1.009 SG. I also raised the temp to 84ºF. I plan to lower it to 80º afterwards.

I haven't experimented with .016, but I would guess from my experience that most macros would be fine there, with probably a few exceptions. For example, I was shocked that hypo killed off my caulerpa racemosa peltata. I was also thrilled!

It also killed off my plague of aiptasias. It would be VERY interesting to find out what salinity is the breaking point for them! Imagine, just running your salinity at .016 or so, and aiptasias dissappear!
 
Ending hypo salinity treatment today! Now I just need a really big salt shaker…

I'm not sure how long I'm going to take getting salinity back to 25ppt. I'm guessing a week should work. I very anxious to get my old tank back. I've just got to be smart, take it slow and build it back from the bottom of the food chain, up.
 
I am excited for you. It will be cool to see the life in your tank rebound while at the same time hoping the pests have been exterminated​!
 
Just back from camping over the weekend. Everything still looks good. I am resuming salt additions today. Several more days of it to come.

I just did a quick check online, and found some barnacle blennies on sale! I grabbed five of them. That was a lucky find! I'm hoping to find some sailfin blennies as well. I want to get the smallest guys in first.
 
Awesome!!! They are really cool blennies. Same species as before?

They are so alert, as if they've mixed energy drinks with cappuccino and high octane gasoline!!! :D
 
Yes, the Panamic or Hancock's Blenny. The same as before. I really like them! Fun behavior, funny looking, and I can keep more than one. Their eyes can move independently. That's alert!

The ulva is getting smaller. I think it's being eaten. Hopefully it will come back as salinity rises. The sagittaria was showing signs of a comeback, until I started adding salt. Now it looks dead.

My turtle grass continues to sprout new blades, but maybe not as fast as the first time. I'll keep pinching them. The manatee grass looks a bit beat up. The shoal grass hardly missed a beat during hypo. They both still have some cyano encrustation. I really like the shoal grass. I think it will fill out the meadow nicely. It grows faster. Its thin blades aren't as tall as manatee grass, but its flat blade shape moves beautifully in the current.

So, the goal with the grasses is to lose the turtle grass completely, then focus on the manatee and shoal grasses. If I succeed, I'll finally have the beautiful seagrass meadow I dream of.

On the macro algae side, first I'll see what survived. Then I'll figure out what else I want. I don't want too much, so I can dose for the seagrasses, not a fast growing caulerpa or other greedy weed. I do hope to have another healthy macro bunch. Just not as fast growing or labor intensive.
