what's happening???

[fishyfish22]

my wimplefish and pakistani butterflyfish seem to be loosing their color, the wimplefish's top half is faded greatly and the pakistani seems to be fading little by little. what do i do? they seem to act normal. also , my small male occelaris seems to be swimming closer to the bottom and sometimes bumps into the sand. what does this mean?

Please post some more info; tank size, water parameters, how long you've had the fish and what you're feeding. Also list all fish inhabitants in the tank. When did you first notice this?

How long have you had them? When did you introduce the last new fish into your tank? How old is the tank?
