I have a 26 gallon cichlid fish tank. I am looking to buy more fish. So far I have 2 red blood parrot fish, 1 black knife fish, and 2 snails. I know I can't have many fish since cichlids are territorial, but what fish would you recommend to buy? Thanks!

Do you have any plecostomuses to clean the inside of the tank? You need to be careful adding other fish as the cichlids are extremely aggressive and surprisingly delicate. Get a book on cichlids. I had 10 tanks of different colored cichlids, brown, yellow, etc. I didn't keep other fish in with them as I had only one color fish per tank.

I would recommend a hammer-head shark, as they are very friendly and playful with humans.
