BEAUTIFUL PICTURESSS!!!!
Hello there and Welcome to the MOORISH IDOL THREAD!
What depths are MI's usually found at?? I'm curious what the water currents are like in their natural habitats and also how much they are exposed to lighting extremes. Also do they spend much time on the bottom. Just wondering if a BB tank would add stress to their lives. Also what size tank do you think is minimum for a MI? Are they from areas with normal tropical water temps (76-80) Also do you know if they sleep at night? If so do they go into rockwork to sleep? Lastly, besides sponges is there anything else they eat in the wild that could be supplemented in their captive diets?? Thanks so much!
MI are found at shallow deapths... mainly where there is a lot of water movement and surge.
NO moorish Idols do not spend a whole lot of time at the bottom but instead more swimming around the rockwork looking for sponges to consume.... they will swim at different depths... but I DO RECOMMEND that you have at least an inch of SAND .. as in very small granual sand... on the bottom because like tangs they seem to ingest a bit for help with digestion!
There are many VIEWS of course, on the MINIMUM tank size for a MI... I have one in a 75... but have only had him now for 8 days.... I personally say that your SYSTEM... must be AT LEAST a 55 gallon, VERY MATURE... minimum of 3 years old... but most importantly have some species of sponge growing on LR.. if you do not be prepared to aquire some very fast, BLUE seems to be a favorite.. in my experience... Also a REFUGIUM FILTERED system seems to be the BEST possible tank host to keep one in... due to the excessive amount of PODS and SHRIMPS that reproduce to give some food to the MOORISH IDOL durring that first tank adjustment!.... mine MUST be eatting some Shrimps and Pods (as in Amphs... not cocos), because he always has a full belly although I do not feed him but twice a day... I have very little sponge for him to eat NOW!... lol, he ate it all!!!! haha.... either he has a secret stash somewhere... or hes eatting Pods and Shrimps... by best bet is the Pods and Shrimps! Moorish Idols seem to do better in a reef tank system than a FISH ONLY system... while NOT being REEF SAFE themselves they do better in an environment of such! I would say a MINIMUM tank length of 4 feet is MINIMUM for a SMALL (2.5 to 3inch) MI..... WIDTH is a biggy too... a minimum of 18inches is ok... they do like to move around ALOT so they must have enough room to "cruise" haha
Yes Moorish Idols sleep at night... they go into a nice little cubby hole in the rockwork and put on their "night suit" they turn a darker color... with less barring... this is how they nap!
Moorish Idols are found all over the worlds TROPICAL OCEANS... therefore a temp of 78*F to 82*F is good for them!
Lastly, besides sponges is there anything else they eat in the wild that could be supplemented in their captive diets??
Their PRIMARY diet seems to be sponges... while this is PROBABLY a HUGE KEY in their survival in captivity and of course in their natual environment... other than sponge growth they feed on clams... dieing maybe.... and some LPS corals and SOME soft corals... while I have NOT seem any evidence that MINE has shown of munching on any soft corals.... he does nip at brain corals.. LOBOPHYLLIA and WELSOPHYLLIA (spelling?), other than that mine seems to ignore most every other coral! They may feed on certain algaes... MACRO but this probably does NOT consist of a primary part of their diet! Again I will say that they do feed off of Pods and Shrimps (live mysis) so its important for you to have a good population of these critters in your tank reproducing before you consider getting one!
Ive had mine 8days... just YESTERDAY did it START to nip at some Frozen foods.... they are VERY PICKY... and very sensitive... not a begginers fish at all... and lol, be prepared to spend alot of $$$ on some SERIOUS sponges and FROZEN FOODS!! as well as some PELLETS and such!
Oh yeah.. I also check at work *LFS* to see why we do not carry spectrum fish foods... the owner said they use to... but people reported that their fish and the fish at the LFS did NOT really prefer this food!...so she stoped carrying it!

, I can NOT get any foods... there is a MINIMUM order and you have to buy from SPECTRUM... so I will have to get something else!
BTW: My IDOLS streamer has DOUBLED in size since this morning since I left!!! unbelievable!! I will try to get some pictures!!!!
