yellow clown goby won't eat

[stlmoguy23]

so i bought clown goby 3 days ago and it will not eat any ideas i don't want him to become crab food. Is this normal?

Mine was the same way, still won't eat much. Seems to prefer brine shrimp almost exclusively. Guess i'll buy some selcon to help give those brine shrimp some nutrition, hope he decides to eat better in the future
