I currently have a 10 gallon and I am converting an old 55 gallon ruby cut fish tank into a 80 gallon tall viv. There are multiple features in the tank that allow the frogs to inhabit the upper portion of the tank. I currently have one Brazillian Yellowhead and am going to get more after the completion of the tank. I know that tincs like the ground level of the tank and dont really visit the upper regions, are there any pdf's that I can put in with my tincs to will live in the upper portion of the tank? Also, what are the benefits of having fans installed in the tank?
