Picked up a 20 gallon tall at Petco for their $1/gallon sale. This is going to be for a qt tank. Should I have gone with the long instead? Or is the tall going to be ok? Only using this for small fish, no large angels or tangs.

This will mainly be used for newcomers as I’m starting a new 100 gallon.Either one is fine. I prefer the long simply for the left-right swim space but they are only (hopefully!) in there for a short period before going on to a proper-sized tank.
Havent really decided yet, probably a HOB with a sponge from my sumpThen you are good to go. Are you going to run a HOB or sponge filter?
