you're thinking clown loach, not clown pleco.The clown pleco is a bottom dweller that requires groups...and grows to 16''. That said, I am not getting mad at you. When we say your tank is fully stocked or that something in your plans is wrong it's not something personal. As Mg said, we all make mistakes, and a large part of how informative this forum is is correction. Your tank sounds very pretty and if you want more fishies I would try and beg your mom into getting another. Keep in imnd that you will be going to college in a few years and they will probably not allow you the 35 hex, though.
no reason why you cant do plants.woops i didnt tyop it right, sorry im really tyrd, i was being devls advacate, i ment what if.... but i am 16 the tank is deeper then long, and i cant do live plants becasue its two deep. but i love my 20 Gal.
you all have to admite that the Hex tank is very cool because you can take advantigg of the levels
