black spots on beta fins

Question
My beta has black spots on his fins. Is something wrong with him?

Answer
Hello Jessica-

It depends on where the black spots are. If the edges of his fins are ragged and have what looks like black dye staining them, then this is fin rot and needs to be treated (aquarium salt is your first choice.) If the spots are just black dots and not fuzzy, then it's probably his natural coloration.

Hope this is helpful!
