Does anyone know anything about horse shoe crabs? Mine never seem to eat and I was wondering if they would eat copepods that I found for sale on internet and does anyone know if copepods are really a good thing for a fish tank? Thanks.:)
 
I'm pretty sure you want to feed your horseshoe crab things like smaller invertebrates, maybe some market shrimp or open some clams or oysters and stuff. Horseshoe crabs will also eat dead fish if you put them on the bottom for it. They're notorious for eating any type of annelid worms and other benthic inverts. If you have any type of shrimp in there, they're going to become food at some point.


Copepods are pretty small and they're pelagic, they live in the water column, therefore not being a food that horseshoe crabs eat on a regular basis. The copepods will be a great food for some fish, they're said to be particularly good for marine aquariums, as they eat algae and are good for fish that are finicky eaters.

What size tank do you have?
 
I imagine very small they will eat copepods but for the most part they are scavengers and will eat anything. On copepods, every salt tank should be default have them. They come in on the rock and multiply in areas suited for hiding.

Try mysis, small krill, small silversides. Considerably less on shipping and easier to find.
 
i have a little one in my 125, it started in our 37 and we moved it over because i was worried there wasnt enough "stuff" for it to eat. Ours digs through the sand a good deal of the time but i have also seen it feasting on various scraps in the tank.. tiny pieces of squid, silverside, krill, exc... we have copepods in our tank every so often.. i cant imagine it eating them to be honest, copepods are TINY
 
mine eats bigger peices of mysis, krill and pieces of bivalve
