I have a 3.d inch texas cichlid that is not moving hardly at all. He is very dark in color and obviously stressed. This morning he didnt come up for food and just stayed on the bottom. Tonight he is just siting at the top in a plant doing nothing. The other fish in tank are fine and the water parameters are fine. This is usually the most active fish in the tank. I can usually tell what the problem is but now i cannot. when i get a chance later tonight i am going to put him in a hospital tank and try to figure out what the promlem is. I will also add extra salt to the water. hopefully he gets better, but if anyone has any suggestions that would be great.
