well i know for a fact that the 3 scarlets died because i discovered them being eaten by the other crabs and snails. after each had died i saw that blue legs had taken their shells, but now they are all abandoned and and have found small shells abandoned too. so there are more shells and not enough crabs. we checked the ph
ammonia nitrite nitrate temp and everything else and they are all perfect. we havn't been feeding them anything because we have no fish yet and we were told that they will survive on algae alone, which we have plenty for them to munch on. is this just a normal thing in a new tank or is something wrong?
