Pufferlover is right on the money! Please make sure that they cannot get out of your tank, it may take a while but if there is a way, they will find it!!! I used to have a gold spotted moray, he would eat krill, shrimp, silversides, whatever I put in the tank, he would eat. Make sure that he has plenty of hiding spots and you might want to feed the other fish first and then him last because eels are very timid and won't get a chance to eat if you aren't careful. I think you will love him! Good Luck!!!
