So a few months back i purchased a 270 gallon tank from a Dr. that was retiring to Florida and couldn't take it with him. He housed 8 large Oscars in it for several years before eventually losing them all to old age. Somewhere along the line he also acquired a male convict that lived happily with the Oscars in this huge tank. I have never kept cichlids really except for our single adult angelfish in our SA planted 75. At the time there was a guy i had met in the hobby that offered to take the fish. On the day of the move, the guy stood me up and i was left with my new aquarium and a bucket with a 4" convict. Luckily i had a spare 29 gallon set up which i quickly set up using things from my other tanks. I didn't know what to do with this fish but wasn't going to just dump it off somewhere. My wife took a liking to him and we've decided to keep him. I am almost to the point of moving our other fish into the 270g and that will vacate an established 75 that we would like to move him in to. I have been researching for days and find it hard to figure out what fish i can put in with him to fill this new tank. NO FEMALE CONVICTS. I would love to experience the breeding but would quickly run out of things to do with the fry. I would love to keep the convict as the centerpiece and grow him out to a huge adult with a hump. Are there any dither fish or anything else that could put together a nice tank set up. I'm partial to keeping things in the same location, biotope-ish. I can do live plants and a nice scape. What would you put together for a complete tank?
