Looks like you're going for the community tank, I have 2 Pictus Cats in my 55 gallon that do a heck of a job cleaning the bottom of the tank, lil territorial though but big piggies, there bellies always look like they are going to pop when they are done eating. But they are awesome to watch swim around the tank cause they are always active and its pretty neat to watch them find food with there huge whiskers. I also have a spotted cory cat whose cute to watch, i need to get him some more friends though. I also have 4 serpae tetras which always school together and are always on the move, sometimes fin nippers but have calmed down a bit. I also have two african cichlids, now before everyone jumps on me i know they should be in there own tank, but they are lil guys now and have beautiful color. I plan on having a true cichlid tank in the future.
