I had a pair that lived for 3 years until I neglected my reef tank and had an ich outbreak which they perished. Last year I added 5. Two died a few weeks and the 3 remaining is swimming around the tank for a year now. Bought a UV to keep the ich in check.
Trick is find an Idol that eat pellets at the LFS. Most Idols at the store or somewhat skinny already. You need to feed is 5x to 10x a day for the first few weeks to gain some weight. Your water parameters will suck with all the extra feeding so prepare for large water changes, GFO, etc. After a few weeks you can cut their feeding to 3x daily and then 2x daily. Diet is 70% New Life Spectrum Pellets, 20% flakes, 10% Mysis and some nori here and there. 300G tank. Idols like to swim. They don't do too well in smaller tanks IMO. When I had them in a 20G quarantine tank they still look like crap even after feeding them a lot. Once they went to the 300g tank they looked healthier after a week
Sorry for the crappy phone pic. Thats all I have to post
