For everyone that has ever questioned how my crabs react to having crickets in the tank....Poseidon (my blue) has like 6 crickets on him while he was taking a nap. Last night Hephaestus (my straw) had like 10 or so with 20 sitting around him. I currently have 7 crabs and 100-200 crickets. I'm waiting til it gets warmer before releasing a good majority of them. I only need 10-20 of them to keep the tank clean.
