Very skinny Acei

[booyah]

Hi...... I got 3 Acei 2 months’ ago two of them look really good. The one is very skinny and looks like his her little belly is sunk in her face looks sunk in also. She seems to eat but not a much as the other fish . She has been this way for some time now. What should I do take her out of the tank and try to nurse her in another tank ? What can I do to get her back to good health? Does anyone know what is wrong with her?
I have another question ?I bought some frozen brine shrimp is it ok to feed to my fish once a week as a treat?

just like people, if fish are deprived of food for too long the muscles deteriorate and you get the skeleton effect. all you can do is feel alittle extra and cross your fingers.

I suggest you put the fish into a tank on its own and look to feeding it small amounts three times per day. Take the fish away from the others as they could be stressing it out. The next thing you know it will die on you and that would be tragic.
Have you looked at some medication as it could be ill!
