A Jack Dempsey lives in tank 25. His name is Bubbles!!! He usually eats 4-5 small squid pieces but he has been getting skinnier so we had to start feeding him as much as he could keep down. Sometimes, Bubbles eats but a minute later he coughs up 2 or more of the squid pieces we fed him. If he doesn’t start eating properly he can’t gain weight and be a healthy fishy. There is no need to fill water because the tank does that itself. We also need to be very careful when cleaning Bubbles’s tank because we feed him before so he will stay calmer. It works unless you accidentally touch him with the algae brush. He will hurl some more. We are trying harder to get Bubbles to eat and hope he survives.
