Hi everyone, I have a 15 inch redtail shovel nose cross in a 125 gallon aquarium. I know that the tank is to small in the long run, and even the short run, and he may be going into a tropical pond, but is there a possibility of him ramming into the glass and breaking it before I move him? Cause he hits the glass pretty hard sometimes. Has anyone had one of these experiences? Will he hurt himself if not break the tank? Thanks
