Hello, I have white sand in my tank, and when I feed my clown knife he gets a mouth full of sand and spits it back out. Is this safe? will he accidentally eat sand and block his digestive system?
Or is he like the polypterus and can eat whatever solid non food items he feels like?
Oh and he is the most awesome fish ever he begs for food. He actually comes out of hiding and stares at me till I get the food out, then he thrashes about once he sees the hikari bag
Oh I am currently feeding him Hikari sinking carnivore pellets because its the only pellet my ornate poly will eat because I am lazy and dont want to have to feed them different foods.
