Hi all, I'm building a tank 4ft long, by 20in wide by 18in deep for my tandanus catfish. Now, this tank isnt going to be set up for a few years, maybe longer, so I have plenty of time to mull over my options. By that time, my catfish will be 1ft+, and might get a bit much for my fire mouth (which I think is a female), but I am a HUGE new world cichlid fan, and have considered various options for tankmates like an oscar, a jaguar, a jack dempsey, or a green terror. Just wondering what ur opinions on a good tankmate along those lines are. I dont want any aggression problems, so feel free to warn me against a certain species. cheers.
