20 gallon is NoT big enough. he has one hide because that's what i have room for. he's too big for the tank. someone apparently felt they needed my digital camera more than me so i'm pretty sure it got stolen. i think at least a 30gal tank would be better... it's just not big enough dude, trust me god i'm really upset i don't have the digital camera. if you could see how much better he looks right now you'd do a dance lol. but the tip of his tail is like crusty and hard and stuck omg what do i do
