I lost one of the males about a week after the female died. Jabba and one other male are still alive. I initially tried shore shrimp but they can't seem to make their tentacles work to catch them and most ended up in the filter sock. Jabba is still very accurate with his arms but the other male has trouble seeing the food and will not take food (dead or alive) from my hand. I have been leaving a couple of live crabs in the tank after Jabba eats. They are sometimes gone and sometimes still wandering the tank in the morning so I am not sure if the smaller male is eating at all.
