My fish are dieing one by one :(
 
Im not sure whats wrong.. I have an orange algae thats growing dispite it being dark with only the tank light. the fish give no indication of being sick before they just end up dead in the morning. They are super busy (normal cichlid behavior) and then belly up 8 hours later. Could it be the orange algae? or maybe something I cant see? The tank is cycled, and i see nothing in the water tests that would show any indication of something bad.

Were it me I would reduce feeding to once per day. You do not say how often you are feeding. I would strive to keep ammonia, nitrites at zero all day every day. Nitrates should remain at twenty or lower anything over 40 and water changes are in order. I would also vaccum the bottom of the tank at each water change a small area and a different area each time. Cichlids are huge waste producers so it may take a little more effort to maintain water quality for them.
