I had about 11 months success with a Moorish Idol that was shipped from Kenya ( I do think that the African ones are a bit more hardy). He unfortunitely died... NOT from Malnutrition but from a rogue crab in my system nipping him on the mouth and slicing it open, quite severely.... I never witnessed this however my girlfriend did. He (Moorish) was apparently picking from the rocks, which he did all day (gutsy little guy that was constantly keen to eat), when he stuck his mouth into the crabs hole after which the crab nailed him. He then swam frantically around the tank and came to a stop in the corner of my 1.5m display. This allerted my girlfriend who then phoned everyone from my firm to my parents to let them know that "Moorish" was injured! Man down!
She understood how much I loved this fish because the night he first started eating i had friends round at my place and when showing them how my other fish ate he decided to brag and devoured a few blood worms as well. The excitement of this little bugger eating ended up with me hugging every person in the room with delight, jumping for joy...... then waking up the next morning wrapped around my new, not yet installed, metal halide light unit, that i had placed on my bed for safe keeping. My girlfriend was on the couch...admin! The cause....A bottle of wine and a bottle of Richellue consumed quicker than usuall. Every time someone at the party chanted "Moorish consume" .....i consumed! My girlfriend filled me in the next day...first had to feed her before she would give me any reaction....like most ladies, they happiest after a meal.....tip for all you peeps that sometime give your tank more attention than anyone or anything else..... haha
The moorish took to food in captivity after 2 days and ate pretty much everything i fed him. He was a young specimen, which most should i say, early eaters are!
I devouted my time to making as happy as possible.... specifically offering him any sponges that i could lay my hands on.
However these were rarely eaten (maybe not the right species?). Instead Moorish's favourite was large LM prawn heads and thick blood worm as well as flakes. The prawn heads i would cut in half when frozen and allow them to defrost. He would eat the brains of the prawn and most of the head out of my hand. he also like pilchard gut!
I heard that Pablo Teapot, Bob Fenners bud, kept a few healthy Moorish Idols feeding them only Spectrum Thera A pellets. Bob Fenner confirms this on WWMedia. I tried to get hold of these pellets but was unsuccessful. Not sure if Pablo's Idols are still alive?
Moorish however seemed to be thriving with the occasional thining of his fin but which always grew back.
He grew quite considerably and pretty much doubled in size over the time that had him.
Moorish never ate after the crab incident as his mouth swelled quite badly and was badly cut... I did however try my best to coax him to eat.
The day he died there was some tears, especially from my girlfriend!
They had grown quite close, even though he was the biggest pest and main culprit for stealing all the food out of all my corals mouths, which she loved feeding (the corals).
O yes.... my Idol was reef safe, believe it or not..... did not tough one of my LPS, SPS or softies and even ignored my coco worms as well as all other invertebra.
Thought i would dedicate this little piece of writting above to him in his memory!
Lastly... I WAS LUCKY!! after a lot of research i realised that, had the crab not got him, the chances of me sustaining his diet in the future was slim and he most likely would of not been around for a very long time. I do agree that we can try, however there diet in the ocean can not be replicated in our tanks at the moment and malnutition is inevitible!
So in the support of conservation of every creature, not just the rare ones, i would recommend that unless one is very sure of oneself that you can give the animal as close replica of its natural habitat and diet that is necessary, rather dont attempt to keep it.
Sorry, got a little carried away with enthusiasm....
Cheers.
