I had my last one for about 5 years in a 100 gallon tank. To learn about them I went to BoraBora and spent a lot of time with them underwater. They are a very common fish and eating is not their biggest problem.
In the sea they take long swims, like 100 yards around the reef looking for sponge. In the South Pacific they eat this lime green sponge but in Hawaii they eat this stuff that looks like dying seaweed that covers everything. After they eat a while, the female who was following him comes and he leaves.
I found a sponge here in New York that grows on wooden docks that they love.
There are very few people who kept them for ten years in a home tank, very few, maybe two that I heard of.
This is Hawaii where they eat the mulm off the rocks. No other fish that I saw eats that.
I made a feeder for them that drops some fish oil soaked pellets into a dish 5 or 6 times a day as they eat constantly. I also gave them that sponge every couple of days.
The Moorish Idol question comes up allot. Here are some recent posts on the subject that might help you. These posts I found interesting and informative regarding the infamous Moorish Idol. I want one.. just will be a while before I try.
Hello all! So I just set up a new tank and I have always loved Moorish Idols. Unfortunately, I have heard so many people that say they never live more than a year in reef aquariums. But, with the right diet and adequate space, is it possible? Please, share your experiences with them and tell me...
