Moorish Idol

This is the infamous Moorish Idol. Here we present one of the most difficult species of fish to keep and raise in captivity. Their popularity increased with the release of the kid's movie "Finding Nemo" but as most hobbyists soon found out, this saltwater fish is very tough to acclimate and keep. Long term survivability of this species in home aquariums is rare.

This fish is colored with white, yellow and black vertical body markings. They are frequently found schooling along the reef and provided that you have a large enough tank, you may be able to keep multiples in your saltwater aquarium.

It is a very finicky eater and to make matters worse, their protruding mouths are sometimes damaged during collection and transport. Another good reason to use the quarantine tank when you first get them is to get them eating without any competition. In the ocean they graze on marine algea and sponges. Having copious amounts of live rock in your tank will provide grazing opportunities in between meals. Try to give them a varied diet of live or frozen marine fish foods.

They can come down with most saltwater fish diseases especially if you're having difficulty getting them to eat. Therefore, use of a quarantine tank with this fish is a must. Keep them in quarantine for at least a few weeks, but at least as long as it takes for them to start eating.

They are true beauties though and if you consider yourself an expert in marine aquarium keeping you may want to try this elegant and delicate fish. Don't cut any corners with these fish and be sure to take your time while acclimating them to your tank. Give them optimal water conditions and please, don't even think about adding them to anything but an established tank after the recommended quarantine period. For most hobbyists, the Moorish Idol is one fish that is best left on the reef for now.
