I need help trying to decide on a bottom dwelling fish. I am looking somthing that is less then normal. It also has to be able to stay around 7-8 inches, because it has to be able to live in a 29 gallon aquarium with 2 African Butterfly fish, an Amazon Leaf fish, and a Silver Needlenose gar. I have been looking into a Bichar for a while, but I am not sure how they would work, considering they get alot bigger in size. I would like for it to take live guppies if possible. I have already had a few different syno. catfish, and a Knight Goby. Any help is greatly appreciated!
