How and what to feed hermit crab

Hello! I just got a hermit crab from the lfs and they said that it'll just eat leftover food and algae. How do I feed it if the fish just eat all the food first? And also what should I feed it?

Hi,

You don't feed it anything. There is more in a SW tank then what you add as food. The "LIVE" rock is crawling with tiny sea bugs. The hermit crab is a cleaner critter, his job is to clean up and believe me the fish do waste and there is always algae...one little hermit will be plenty busy working to keep the tank clean, with plenty to eat.

This sounds like the first time you've had a hermit so here's a heads up:
If one day you look in your tank and you see that the shell is empty then look farther and see what looks like a dead crab in your tank, relax. It probably just molted (shed its "skin") and is hiding for protection till its new "skin" hardens. At which time it'll move back into its home.
But, every time it molts it grows so when it does, start planning on getting some empty shells of the same style and various sizes so it can eventually move to a bigger home.

Any empty snail shell similar to there old one. I use empty cerith and margarita shells
+1

But, you'll have a hard time getting a hermit that lives in a cerith shell to move into a margarita shell. You'll have much better success if you use a shell from the same species as the one they're currently living in now. Plus, use a variety of sizes. Don't just put one shell in and expect him to move into it. He may even just go back to his old shell till he get's too big for it. Even hermits like to have the freedom to choose.

I bought the 12 pack decorative shells like the one on *********** at *****. They look really nice but my crab didn't bother with them, so I just returned them.

My red leg when I bought it had some shell that looked like it came from a fighting conch but idk. I got it at *****, just so you guys know, I don't buy fish from them except for the damsel and my freshwater fish cuz I get a 30 day return policy if they die. Not availible for saltwater. The fish always seem to be unhealthy.
