BRUNER247;4519285; said:Massavore pellets might be the best sinking pellet, but they are not the best pellets for piranha. Bio-gold+ is the best pellets for piranha n helps their color also. N your question about hunger n cannibalism. Piranha can n will cannibalize right after a meal.cannibalism isn't always about hunger. More aggressive pygos n macs can be very bad about this. Rbp are hit n miss sometimes.
What is the biggest difference between Massivore and Bio-Gold?? Im using Massivore now, but it is expensive. I could easily burn thru a bag a week.(7 RBP's at 6-7 inches) Mine eat anything that drops in the tank, fillets, worms , pellets, occasional feeders.
