OK i was bored and went to the bait shop yesterday and bought large silver roaches (the fish) i gave one to my p's and they went nuts for it. And now today they are acting more crazy and territorial then ever!! i reached in to move a plant like i do every other day and they tried to attack me instead of running. Whats in this fish or what else could it be? they are chasing each other and attacking everything that enters the tank!! the bait fish were not cheap and i got 6 of them, and had to freeze the rest as they did not acclimate to my feeder tank. but before i feed them the others are they good for feeders?
