My cousin bought 1rbp about 3 months ago he fed it mostly worms and goldfish(which are bad like i told him) but anyways Then he got a bigger tank and bought another rbp and has been feeding them mostly shrimp and worms with an occasinal g.fish. Well i got my 2 rbp about a week before christmas. They were the same size as my cousins. But after about a week i noticed mine seemed to be getting alot bigger than his 2 fish. Why are mine growing so much faster then his 2 fish. We have exactly the same size tank just curious? By the way i have been feeding mine mostly krill. My to red bellies are around 4 inches now and his still are likle 2.5 inches same length they have been since he bought them. Is it just the food i feed them or is it another factor I would like to know this. Thanks for the help.
