I had been feeding my pirahans pellets and they loved them. i got an exedon that was toobig and scared the 1 in ch priahans into there dens, but i took the exo out and now there are fine, but they dont seem to be eating pellets, i put a feeder in there, but i killed it first, they eat that but they wont touch a pellet, do you think they will go back to eatign pellets in a day or 2? please help me, i dont want my p's to starve and i dunno if this has anything to do with it but they go to top water but they dont touch the pellets
