What did you feed it before you changed the decor? and when you changed it did u wash it? There might have been sometype of parasite.

decor is cleaned and washed, plus the tank has a uv sterelizer, also, aros tankmates are still pigs when it comes to food. i came to a conclusion maybe his taking sum time off from feeding and probably lost his appitite....i hope he gets it back. only diet he gets is hikari floating sticks, silversides, and krill...
