Is there any smaller, carnivorous catfish that looks like a catfish (like a redtail or TSN or Gulper) that can live happily on it's own in a 20 gallon?
I already have the tank, that's the thing. It's getting emptied soon so I wanted to get a catfish in thereIf you get a 20g long then consider the cetopsis coecutiens. Cool oddball and will voracious in it’s own way.
The thing is...I hate puffer fish. With a passion. I hate their teeth. Any other recommendations?If you're wanting it stay in there for life...not a catfish but carnivorous fish that would do better in that size tank my vote is Congo Puffer. Super cool lurky type puffer that ambush from the sand/gravel bottom.
Most of the catfish that would do well in that size tank permanently are not predatory, i.e. Cory Cats, Porthole Cats, or Wood Cats (Tatia).
I cannot find any pictures of this Platysirilus mucosusBatrochoglanis raninus is a great little RTC shaped cat, platysirilus mucosus look tiger shovelnose to an extent but 20g would be a little small for these, mine seems to have stopped growing at 5"sl.
