No way, 2-3 inches is huge. I can see why you guys are saying a 5 gallon tank is way too small now. Those little guys I saw at the pet store were probably just babies.

I've read they can get up to 2.5" in captivity, sometimes bigger, but I'm not sure if that's the case for all species. I've seen some that were pretty small too - around 3cm, but I'm guessing they might still be growing.
