leucomelas crowding

:) I'm looking at some leucomelas, and found a great deal for three of them. One male, two females. Would a 12 x 12 x 18 be too small for them? What if there is lots of hiding places? :confused::confused::confused: Thanks, Chris :D

Hey everyone, I've been noticing my display leucomelas group have been bunching up in in one small area for the last few weeks. (5 Leucs, 55 gal.) I've had these frogs about six months and they're roughly 10 months old. Is this a normal thing for Leucs or are they depressed, lol? I'll attach pic...
