The Moorish Idol Thread

Yea, I guess San Diego is a bit quiet compared to Manhattan. If you think it's quiet there, you should see where I live. Hardley anyone around. The biggest traffic I see is the Sailors going to the base in the morning or the field worked gout out to the fields to pick Strawberries.

Other than that, it's really quiet and laid back. That's why I like it here. But we do get some traffic congestion out on the big highway on the weekends. People heading north to the dunes on Friday and returning home on Sunday. It's always a big back up at those times. Otherwise, it's fairly calm.

The wife and I would both like to visit the big apple one day. Just got to figure out how to fit it all in the plan.

Take care.
 
Update on the new Zanclus. It's been almost 8 weeks and he is happy, healthy and still a bit aggressive. Doesn't go after smaller fish, rather the Coradion, which does have a similar pattern (to another fish, anyway). I removed him for his own safety.

Eats like a proverbial pig, has put on lots of weight and the streamer is quite long. Loves bananas, not overly interested in the commercial angel-sponge food (from Thailand), but does eat a small amount. Flakes are the absolute favourite. He does pick at the gorgonians, but does no real damage.

Sorry the shot is not clearer, but.....

Crusty, I did like Calif. It is very different, especially spread out. Here in NY we have no open spaces between towns. I would have to go an hour to find that.
The railroad that I took to the city carried over two million people every day. Thats the main reason I retired. If I never see Manhattan again it will be too soon. Unfortunately I have a job there tomorrow so I have to go. This is my only customer in the city but he gives me a $500.00 tip as soon as I go in his door. I hate to give it up.
 
Beautiful idol you have there, bud. Has anyone come up with an explanation regarding why they get these long hard dorsal fins in place of the streamers? One would expect it to be dietary in nature...perhaps an overabundance of a given mineral (calcium?) in their diet in the aquarium environment, vs. the normal sponge diet in the ocean. Although, did Paul mention seeing this in some ocean specimans as well? Very interesting.

One of our locals and I were discussing Idols this past few weeks. He theorizes that Idols may be gleening some necessary nutrients via natural sunlight exposure vs. the home aquarium lighting that makes or breaks them in the captive environment. Anecdotally speaking...outside pools of captive Idols in Long Beach and Hawaii public aquariums are thriving, whereas they don't live in their inside aquariums long term. Sunlight-driven algae diet contributing perhaps, as well? I also like Paul's theory on solitary idols not doing well long term.

I'm now the proud owner of a large speciman as of a couple weeks ago. He gets natural sunlight in my 360g reef tank, eats Nori, Spectrum pellets, mussel, squid, mysis, etc... Still thinking I should have multiple ones together, though.

Hey everyone, here's an update on my Idol. He's still doing good and growing. He's now about 5-6 inches long nose to tail and is fat. His dorsal fin has started to grow the long streamer once again. However, he still has the long hard dorsal fin that grew in place of the streamer late last year. Here's a pic I took of him tonight. I'm also going to post a couple of new pics of my recently aquired fish in my build thread.

Thanks for the compliment.

Interesting theroy you have there. I haven't been back to LB since I got my Idol to see if their Idols fins are the same. Mine has now started to grow the long streamer once again but still has the hard long fin. However, his streamer is a lot thinner and more ragged than before. Possibily from playing in the water stream or it catching on the rocks.

I've noticed that my Idol likes to play in my C/L return water stream. On the left side of the tank down near the bottom on the side, I have 2 X 1 1/2" returns from my OM 4 way that are hooked up to a Sequence barracuda so it flows about 3500 GPH from there on a random basis. I've noticed that my Idol like sto play in the stream when that return is open and flowing a lot of water. Kind of like a swimmer does in a staionary lap pool.

Mine is still eating just about anything I put in the tank. Since he now feeds with the other fish, he dosen't seem to be interested in any of the sponges that are growing in the tank. I do see him picking at the rocks and sand some. Not for sure what he's eating from there. I only feed the tank once a day so he's getting something else from inside the tank to feed on.

Good luck with your Idol.
 
Great thread guys it took me about 2 days to get through it but totaly worth it! Anyone know of a sponge in South Florida these guys would munch on?
 
I would like to thank everyone for their information they have shared in this thread. I have read it several times over the years. I recently lost my powder brown tang, the tang prevented me from adding any fish due to it's temperment. I went to the fish store to look for a new fish when I spotted the Moorish Idols that had come in. I sat and watched them for some time, even having the store feed them. Two of the three were very active and intrested in food when feed. Needless to say I bought the two and brought them home. I drip acclimated them for about 2 hours. I was going to QT but decided to put them in the tank right away to lower their stress as much as possible. Also the tank has been set up for almost 4 years, so I felt it was the best place. I hope with the information here I can keep them alive. If I remember right some one said they like a purple sponge? I have some growing here and there so I hope that helps them in the long run. I will add a few pics and have more if any one would like.

Thanks Ron

Though I'm a proponent of quarantine, I think you made the right choice. These fish do best if put into a good environment immediately. Your MIs look great. That sponge will work wonders for keeping them interested in eating until they get settled in....as I'm sure they already are.

If you're not already feeding Spectrum Pellets Marine formula, please do add it to their diet. Get the small 1mm size pellets, and they'll thrive on them. Best food I've seen so far to keep them long term, and lots of anecdotal evidence to support that it will sustain their nutritional needs.

My Moorish Idol is now fat and healthy and thriving in a reef tank. Cares little about my corals, but loves Nori seaweed, and eats Spectrum Pellets, frozen mysis shrimp, mussel, squid, and anything else I throw into the tank. But the Spectrum food is the foundation.

Good luck with the Idols!

Well bad news already, I was watching them and the both started tearing my candy canes apart. Out of the tank and into my FOWLR the went. Don't know what I'm going to do. I will do my best to keep them happy and if the do well, I will find them new homes. Might keep them in that tank but one or both will have to go.(Only 90 gallon)

They love candy canes. I think they gave the coral the name. I'ld rather have the MIs over the CCs.
 
I love both, If they love candy canes, the rest of my LPS would be next. The pictue I will attach will show you how the looked back in Jan. The have grown to the point the touch all around.

Man, you have a lot of them!!! They are beautiful!!! My CCs went to the refugium when I had my MI, and I missed them. Even if the MIs begin to take regular fish food and ignore the CCs, they may one day decide to go to town on the CCs. They are beautiful corals, but can be a treat to MIs. I posted this long time ago and this thread now is huge. Perhaps get the MI to eat small pieces of cut Priscine Energetics mysis shrimp. Here is the key...cut them into tiny pieces, half the size of brine shrimp. I just take a small piece of frozen PE mysis and a sharp knife. Cut 1mm slices and that is it. Put just a little bit in the tank at a time, but do this frequently, especially when they are eating. Don't freak out if the MIs don't immediately eat out of the water column. They will likely blow on the small pieces that have fallen onto the bottom of the tank and eventually eat one. They will initially shake their heads several times as if they ate the worst tasting thing in the ocean, but they will keep picking at the pieces on the bottom. Keep the pieces small (did I already say this?!) Do this many times a day, feeding a little at a time. Siphon out any small pieces that have been on the bottom for 1/2 a day or so. I just use RO tubing to siphon the pieces off. Do frequent partial water changes to keep the water quality high. This should work. When they start eating out of the water column, you can try some brine shrimp and very small pieces of scallops. Best of luck!!! If they are actively picking at rock and the glass, then that is a very good sign. Just be persistant with the frequet small feedings. You will likey become excited to watch them take a few pieces so it won't be too boring when you pump your fist with happiness. I believe in using a 30 gallon QT with a protein skimmer and hang on pump (I use an Aqua C remora and an aquaclear 500). They like a decent amount of current. I like a 30 gallon with small to medium fish. If a fish is ever too large for a 30 gallon, then I don't want it. 30 gallon tanks are small enough to allow effective water changes if needed, but big enough to allow decent swimming and dilute toxins. Don't crowd the QT with a ton of rock. Keep several pieces of rock in the QT and keep the area in front, behind, and the sides open so the fish can swim all around the tank if needed.

I had my MI for 4 years and he died in a move of 440 miles. I crashed my tank with the move and I lost my beloved MI.

However, last week I went to the LFS and I found a small 2 1/2 to 3 incher eating and I had to take him. I had a QT running and ready for 6 months, so I was prepared. Use an "aged" QT if you can. Most people that fail with QT basicly use a cruddy glass box. Make the QT a decent investment and you will be rewarded. He now is in the Q tank and doing well. I will treat a MI with copper if needed. I am a big fan of hyposalinity and QT. However, MIs sometimes will need to be transfered to a DT if they start darting around in a Q tank. I don't think 7 days of raising the salinity would work, thus I will treat with copper if needed. Buy the copper test kits. I firmly believe that infections do these fish in fast as their insane metabolism increases even more when they are sick. Keep them calm and control disease and you will be in good shape. If this one survives, then I am 2 for 2 in getting the fish to eat regular food and survive. I firmly believe you need to have them eat prepared foods to suppliment anything they eat off the live rock and sand.

Hi Ron,
Sorry to hear that your Idols started eating your candy cane's. That was how I aquired my MI. A local reefer had to get rid of him as he was eating all of his Zoa's. Since I only had a small patch of Zoa's, I didn't mind as I prefered the MI over the zoa's.

fast forward a year or so to this past weekend. MI has been doing great, eating nori and even pickets pellets that didn't sink off the water surface. Well I was looking at selling my smaller setup with a little grief from the Mrs. I decided to try a experiment. Since there had been no Zoa's in the tank for over a year, and the Idol was "conditioned" to eat food i served him, I went and placed a rock of Zoa's back in the tank. They have been in there for about 4 days now and he hasn't even taken a first look at them. Only time will tell if I've actually "conditioned" him to eat what I provide.

Good luck with your Idols.
 
Thank you, I new the risk when I bought them. Having a second tank in place if it didn't work was part of my plan. As you see my tank is packed, there is nothing like trying to catch fish in a full 180. How long do you think the can stay in the 90 gallon? They are about 2.5 to 3.0 inches right now. When I left this morning they were swiming together with my Porcupine. I think he was happy to have friends.

Ron
 
Try catching on in a 3' deep 400G tank. That's why mine is still in there. ;)

They should be fine in the 90 for a while as long as they are eating and have swimming room. They love to swim if you haven't noticed.
 
I wish I had your problem.:D

The rock work is minimal and open. They seem to be picking at the rock and some food so time will tell. I'm thinking of adding a 6 foot 120-150 gallon to the main tank system and moving them there. Work hasn't been so good as of late so my income has gone down.

Ron
 
Ron, that 180 does look packed!! If the MIs adapt to the 90 and the 90 has plenty of swimming room without too many other fish, then the MIs should be able to live in the90 for quite some time--however, I think they do best in larger tanks such as your 180. Since they are small, they should do ok in the 90 for now.
 
Hi guys,

I want to get a small Moorish Idol (2") for my new 82g tank. I know that the one from Hawaii is a little hardier so that's the one I will be getting. I am setting up a 10g QT right now so it should be readly in a few days. Do you guys think a 10g is ok to qt a small MI for a few weeks? What's the most common disease for MI? How do you guys qt your MI? Does anybody has a problem with their wasses, clown fish, tang, anthias and goby with MI? Thank you guys.
 
i just got a 200 buck acan frag, my first acan , and my idol instanly destroyed it what a sob, he dont really touch my zoas, candy or my sps or clams i dont know what to do im torn lol any advice?
