arrow crab help

got an arrow crab! dont know what it eats though, besides bristle worms. do i have to feed it, or will it just scavenge any leftover fish food or algae or what? thanks.

 

Hope you don't have any corals. Arrowhead crabs are NOT reef safe & they pretty much eat whatever it wants. If you don't keep it happy, it will kill your fish by spearing it with it's arrow aka the reason for it's name "Arrowhead". It will eat, worms, snails, shrimp, other crabs, coral & fish.

 

WHAT thats not what the guy at my fish store said. its pretty small though. i only have like 2 other corals. but what do i feed it?

 

They never do!! I did the same mistake, when it died I didn't replace it. It will eat whatever you give it. It's not picky flake, pellet, etc....

 

Here's a pic of it in my old 29gal. Note in the picture all the empty shells.. Yes, it killed them all...

 

wait, who never does what? and so i just put flakes in, let them sink, and let the crab find them later?

yes, arrow crabs are great scavengers and will track down anything in your tank thats edible you do not need to target feed it, it will find food

The guy at the fish store. Yes, he will find them.

 

LFS "Local Fish Stores" never do. Very rare do you find a store that has a clue of what they are selling & two that will sell just to make a buck. Even though the end result is that all they do is make a customer not return or even worse that customer gets out of the hobby.

Don't worry. Whatever sinks & he sees it, he'll eat it. Trust me!

 

ohhh ok thanks just to be sure, my hermit crabs are safe, right?
