I'm getting worried. My fish are acting fine but they look lousy. One looks like he is wearing black lipstic and has some black spots on the edges of his fins. Another fish has a sore on his side that looks like a zit, a couple other fish look like their veins in their fins are ready to pop. But half of them are perfectly fine. Why do their fins look like they are almost bleeding internally, what are these sores, and what are these black marks? Could it be from adding plants? I noticed this start the day after I changed the water and they had a (in my opinion, quite violent) mating party. The following day I added plants. What should I do? Should I treat with salt? Can I treat with salt while there are eggs in there?
