Iooking into getting one. What exactly do they need to be fed. I know it said hard shrimp but what kind? I feed my fuzzy dwarf lion ghost shrimp. Also would he be ok in the tank with the fuzzy dwarf cause he likes to eat my other fish. He ate 2 out of my 3 damsels. Not sure why he won't eat the last one. It's a yellow tail damsel. Anyways. Would he be fine in that tank. It's 30 gallons and those are the only 2 fish I have and a small hermit crab
