Thanks for the responses, all
So was curious how much digging/rearranging all y'alls did? Just recently moved a pair from a bare bottom tank into a temporary tank with substrate and they dug the living hell out of it. Considering that their final destination was supposed to be a moderately planted tank, I'm wondering if this is normal behavior or if they are just pissed at their accommodations?
Also curious if you guys think they could stand being in a 90gal with some Hemochromis lifalili? I have my doubts, but I am trying to reduce my footprint a little in the basement.
