HCA: Hermit Crab Association

What are some of the things you feed your crabs for calcium.

They have constant access to cuttlefish bone, powdered oyster shell, egg shell and shrimp exos

Mine get egg shells from my mothers chickens, crushed oyster shell, crushed cuttle bone and Mineral blend from HCP (but I dont know if that has calcium in it)

Okinawan Sea Coral Calcium with magnesium supplement powder, crushed oyster shells, cuttle bone, crushed coral, coral, shrimp exos, hcp mineral blend, suebees mineral blend, sand dollars, leafy green veggies, whole anchovies, nuts, apricots, figs, oats, oat straw, Okra, sardines, salmon, just to name a few things..

Oh ya only a FEW!

thought it might help give ideas to others..lol.. when you have a hermit crab dollar store you have lots of food on hand..

Ya I bet!! Hahah you gave me ideas

I have crushed oyster shells mixed in my substrate. I also use calcium sand. Looking back, using calcium sand wasn't the best idea, because it's so expensive, but it works! I assume my crabs also get some calcium from the exoskeletons on the shrimp I feed them. I will occasionally put cuttle bone in my crabitat, but my crabs have never seemed to take a liking to it. I also have the cutest calcium chew toys that my crabs seem to love. You can see claw marks all over them!

cuttle bone (they don't seem to care about), eggshells (they prefer to break themselves), ground oyster shells, fresh foods (broccoli, etc) and several of the kibbles I have bought from the Hermit Crab Patch have it added as well.
