I am thinking of getting a 40 gallon breeder and I am wondering if I can do cichlids in it. If not I would also like to do small schooling fish.
I second the red wolf, I’ve had mine for roughly a month and love it40 breeder is probably too small for exodons. To get a good sized shoal but keep up with the maintenance, 55 is a better size.
Red wolf would be fun, not a cichlid or peaceful tetra, but cool fish.
Otherwise I would say an acara pair or convict pair with some livebearers or Buenos Aires tetras as dithers.
Jewel pair could be fun too.
