hey ive had an ornate bichir for about two weeks now (about 15cm) im aware they should be fed bloodworms but my clown loaches and BGK get them as soon as my hand goes in the tank. The bichir has eaten a few penguin tetras and platys so its mouth is pretty big haha, so was thinking about throwing something a little bigger in the tank for him that the other fish cant eat? What would you recommend? sardines, small prawns etc...
