My land crabs eatting their substrate?

[PapaJT]

I have some Indonesian Land-crab (Gercarcinus ruricola) and they keep eating the substrate. I am using Zoo Med's "Compressed Coconut Fiber Expandable Substrate."

Should I be concerned?

They are probably foraging for bits of food.

 

[Cohazard]

what are you feeding them and how often?

 

[busyfishing159753]

I have some shredded cabbage in a dish in there..Is there something better? I just picked them up 24-48 hours ago.

 

[Jfitz]

usually the case of eating substrate is due to malnutrition...

 

[Cohazard]

I don't know squat about crabs (other than you don't bring home a girl home who has them, especially those big ones), but my money says that cabbage isn't enough to sustain anything.

Google land crabs, and I'm sure you will get all kinds of better advice for what to feed your crabs.

i would look them up more...arent most crabs carnivorous scavengers?

They make a prepared crab food.The cabbage has no calories or nutrients, just water.

They need calcium too.
