High Quantity of Fibers Daily

Fibrous food like peas and leafy green vegetables are good but not every day. This food should be given only once or twice a week. You can use Small Granules Fish Food (Amazon) for better results.

Digestive Problems

If your pet is eating some non-fish food from time to time or some dangerous things like algae, then it can face some digestion-related issues. You should not let your pet eat the green or brown algae, and for this purpose, you have to clean your aquarium completely.
