my danios fins are turning this red-orange color :-[ whats wrong?
Hard to say without actually seeing it. Are the fins starting to fray? If so, it may be fin rot.
no, they aren't frayed. they just have these red streaks (my leopard danios have yellow streaks) through their fins. it's not affecting all of my fish. just about half.
could it be Haemorrhagic septicaemia?
Sorry for the delay in responding - Were you able to figure out what was happening with your fish? From what I've read, fish with haemorrhagic septicaemia will have lesions.
