I am guilty of this one... with most of my grow out tanks. It's hard to move monster fish around when there are obstacles in the tanks...fish panic when they sense/see nets and ram into stuff. 80% of my tanks are for growing out. I do, however have a few tanks that have driftwood and/or plants in them.I know I am stepping on some toes but I cannot stand bare tanks. Nothing but fish, no substrate, no plants, rocks , wood. Anything. Makes me feel sorry for the fish and science has proven that it mentally stunts the fish
The fish would be traumatized
A 50 gallon with a foot long pleco and somewhere between 300 and 500 platies.
