Hey guys, so I got my first fish, a alleni damsel or neon-blue damsel and he's alone in my new 29 bio cube tank. The problem is when I add pellet food is gets sucked right in the filter. If I turn off filter my wave maker gets exposed and starts churning water. So I've turned them both off so he can feed. Is it ok to leave these off for extended periods till the fish eats? Should I try a different food that doesn't float?
