hm but the problem is they only eat whats on the tanks bottom, they wont eat blood worms cause by the time they reach the bottom its already eaten by others haha n they dont come up to the surface to eat the blood worms..
Mine never feed from the top, most people say as the get bigger they learn to eat from the top. My biggest is 6" and Iv only seen him take a pellet from the top twice since I got them (7 months ago)
I would ya. I have a variety of fish in my pool so there are sinking and floating types. SO if they have they need to, they can start surface eating. Just stuff those bellies and they will grow.
