So I just picked up a new Jardini 6" on craigslist for 60$ instead of the price of 200$+ at a LFS. The color is great for a 6inch but the tail mentioned by the owner was attacked by blood parrots. The top dorsal fin looks pretty ugly. I am curing it with high temps and aquarium salt along with fin medicine. I heard of trimming but by the looks of it, what do you guys think?
