ok...i recently have set up a new 58 gallon breeder style aquarium with one 11" black belt, one 6" jaguar, and one 5" plecostomus.......( i know my tank is too small, but i have heavy filtration and i do frequent large water changes...... i am also getting a 100 gal bowfront in december). i used to have a large channel catfish in with them but after realizing that their was no way i could accomidate such a large fish, i gave it to my friend for his indoor pond. but now my tank seems to be missing that something that only a catfish can give an aquarium. so heres the question.....what kind of catfish should i get? i'm looking for something that gets large, but not ridiculously huge, active during the day, and interesting.........any suggestions will be greatly appreciated.
