Alright, so i have 2 hides on each side, i have a 20 gallon tank. Is there such a thing as having it TOO crowded in there? Do they need alot of open space? I've recently added some things to it and it's getting KIND of cramped, but alot of it is just like branches.

Is this okay, or is it better to just have a more simple setup,and not alot of things in it? He has lots of place to hide, and want not, so i figured it may make him more comfortable?
