OK So after over a year of collecting, saving up for and planning equipment, I finally am going to start filling this tank TOMORROW!!! Finish plumbing the tank tonight and start the RODI to fill up my mixing station. I was thinking of making some minor changes in my rock structure, but have a couple questions first.... My tank is a 65 gallon so I don't think I'll have any large livestock
1. What is an ideal size gap for most fish to swim through?
2. How much force could fish put into a hit if they accidentally bump into a structure? Is it possible for a fish to destroy a rock structure? Each rock I placed, I wiggled it a bit to make sure there won't be any boulders falling on the fish. Anybody have any incidents where fish caused rock to tumble on themselves?
