In my 80 gallon I have 13 reds ranging from 5"-7 or 8" for my largest. Also in the 80 there is a little red belly who loves to hang out underneath my overflow box for my wet/dry. They will be moving to my 180 once I receive it and get it cycled. I have a 4" Altuvei which will be going in the 80 and I plan on putting a divider in the 80 gallon tank and purchasing a rhom to share the divided tank.
