I don't know what to keep in a 4 feet tank. It doesn't have to be a fish only, it can be reptiles and amphibians too.
I don't want to get something that will make it feel pointless and boring until I am not connected to the whole experience.
I want something personable, engaging, something that will inspire me to provide the best deco in a 4 feet tank.
Any suggestion?
Okay, now that my computer is working:
A warmouth sunfish gets to approximately 8" but doesn't need a massive tank because they don't move too much as adults. They're kinda like really pretty North American oscars. Lots of personality, nice colors, lots of intelligence. Also, they're not terribly aggressive. The downside is a full-grown warmouth can open its mouth just about enough to fit a golfball. You can't keep small fish with warmouths. Well- not for very long.
