That smaller fish in the background, which looks like a female, isn't in the same tank, is she? If she is, both fish are in some serious danger and should be separated ASAP. Males and females will fight to the death or to the point of severe injury under all but only the most carefully selected, short-term breeding conditions.
Your male's fins look a tad ragged. Did he comes this way, or is this the result of fin-nipping between the male and female providing they are being housed together?
