Whats The Minimum Tank Size For An Adult C. Delphax?

[Starfishpower]

iv got 2 corys, i think they are both c. delphax. one is already adult size and the other is just starting out. what would you recommend as the adult tank size for these fish? i am looking at a 20 long but if that is too small let me know.

corydoras like to be in groups so if possible get some more and keep them in a 30inch or 3ft tank.
if you plan on having other fishes in the tank then go 3ft or bigger.

ok, ill see about moving up to a 30 gallon. it shouldnt be too much more, though it is pushing the boundaries. thanks for the reply.
