I have an Albino Tiger Oscar that is about 5" long. He is in a 55 gallon tank. Right now there is a Striped Peacock Eel, which stays inside a piece of driftwood, and a Pleco, which hides too. I would like to have 1 other type of fish, but everything I put in there, the Oscar kills. For example tonight I was at the pet store and the guy told me that I could put a 6" clown knife in there without a problem, well I did and the Oscar killed it in about 5 minutes. I had a Texas Cichlid in there and it lasted about a month and finally died from wounds inflicted by the oscar.

I need to know what to do. I don't want to get rid of the Oscar because he has great color for an albino, but I would get at least one other fish.

Any suggestions would get great! Thank you in advance!
