LF SW feeder shrimp

[intarsiabox]

I've seen them at place's like Big Al's and PJ's pets. You could set up a small tank, buy a few and raise them yourself. There's not a lot of "healthy" and cheap options that I can think of. People breed molly's as feeder fish as they can be accustomed to live in salt water but how good they are for marine species as a diet has come into question. I am assuming you are looking for live foods so you can see the frog fish in action.
