fin rot? or just a flesh wound

Part of the reason I suggested the medicines I did is that Melafix especially will help heal your fish's fins regardless of the source of the damage. You did mention having some rough rocks and spiny plastic plants, which I wouldn't rule out as damage-causers. It might be best to replace the sharp stuff, but the melafix is still good for any sort of torn fins. The pimafix, on the other hand, is purely antibactierial/antifungal and wouldn't be necessary if you think the torn fins are being caused by physical damage.
