i've been looking for someone with a decent amount of experience with tincs, as i'm planning on getting 2-3 for my first frogs and have ordered a 16'' cube viv (approx. 18 gallons) but i'm thinking of getting a 19'' cube instead (approx. 29 gallons) so i can properly house 3 tincs in it. I've heard that they are on the aggressive side of the scale, would there be problems if i were to get 3 tincs in the 16'' cube? if so would they fair better in the 19'' cube? or should i just stick with a pair in the 16'' cube? thanks for any help or info.
