as long as your parameters are inline, i would look into a derasa clam. you can get them in oranges and blues. i think that would definetly add some color.
and have you changed your bulbs? the color in the first pic looks a lot more whiter/crisper than the second pic. maybe its just the w/b on the camera.
i thought about a clam but my hermit crabs killed a cleaner clam i stuck in the display tank. anyone have that issue?
teen - the lighting is just the camera, the first pic was also taken at night and the second was taken during the day.
thanks for everyones suggestions
