Answer
Hi Cindy;

Your Cobalt Cichlid could be bloated, or if he is just acting normally he's a good eater. If he is indeed sick I would recommend getting him into a hospital tank. Just a bare 10 gallon with no gravel, no filter and no decorations. It only needs a bubbler, heater and lights. Make a 50% water change in it every day since there is no filter. A filter would remove medication if you end up using any in there. There is a condition know as "Malawi Bloat". It is very difficult to treat and often fatal. Here is more about it;

Let me know if that looks like what your fish has.....
