Hi, i'm setting up a 2 foot x 12 inch x 15 inch high tank and wondered if I could get a decent sized shoal of congo tetras in there. The tank will be heavily planted with a group of albino corys as tank mates.
The minimum size tank for Congo Tetras would be about 3ft long. If you want a lot of them (say 10-20 individuals) then I would look at a 4ft or bigger.
