mine is a pig.
i have had him for a long time and he ate flakes for a long time.
he now eats:
pellets,
wafers
sticks,
and anything else that sinks (including flakes)
he likes to nibble on noodles (don't ask, it was an accident.)
and a tip, more people will know what you are talking about if you call it a rainbow shark.
