will be the addition of a shell in a tank of freshwater fish to kill a fish?
I put a large shell that I had for a long time in my new freshwater tank. I have a small shark in the tank … Clean off the helmet, but when I put in the tank, began to disintegrate off-types or waste "a little loose on him. my shark eats the rest … might be harmed?
Perhaps the shark is one of those bottom-feeding? or need for an expert's animals. or see, ask questions and make people do or think it might kill her. or maybe just take the shell if you have too much trouble
