It’s about 7-8 inches. So far I can only get it to eat super worms. Been on it for 2 day’s. Is it bad to only feed it super worms for the first month or so?
If it eats superworms, I'd bet that it will also take frozen krill or earthworm pieces as well. You can buy a tool at fishing tackle shops that consists of a small squeeze bottle (eyedropper size) topped with a hypodermic needle. It's used by fishermen to inject a small quantity of air into an earthworm to make it float up off the bottom. It works perfectly to turn sinking food into floating food for surface-feeding aquarium predators like arowanas.
