i have a large crenicichla, shovelnose, large oscar, and a large parrot fish my water is perfect and the fish clean up all the left overs. As far as monkey see monkey do goes all my other fish eat anything i put in my tank including my fingers. I have gotten him to suck in some frozen silversides but he pretty much immediately spits them out. I know feeders are bad for them to eat but i was wondering what if i froze the feeders to try to get him used to dead and frozen food? And i figure this would eliminate parasites from the picture. And when you say tilapia filets what kind of tilapia? like the stuff at the grocery store for people to eat? It has been 9 days today i didnt realize how long i could go without feeding him i guess i will just keep trying this damn fish is driving me nuts!
