i had my first silver dat on pellets but i had to give him away. he was eating feeders, then i started throwing in pieces of shrimp with every other feeder, then i would just throw in shrimp, then i would stuff the shrimp with massivore, then in about a week he was eating strictly massive, i hated letting him go, i have a tank big enough now, so im prepared to keep one for life this time.
