My fish has been staying near the surface of the water, and is moving very little. What should I do? Is this normal?
It is possible that the fish ate too much, or that the blood worm had some bacteria. Also, it is important to clean any leftovers of blood worm from the water. You can distribute the food in five takes a day and with little quantity, in this way you can control the amount that the fish eats and avoid this situation.
All the best,
