when we were working in the garage recently, I found a collection of rocks and put some in a container to bring in the house for the smallest fish tank….

the fish didn’t want to move as I was putting the rocks into the tank, which was missing coverage on the bottom…

once done, the tank looked better and the fish seemed to approve;-)…

last year this tank held pond plants, but as the fish have grown, it seems like a good idea to provide a bit more room…
