My female betta is getting over a case of ich which killed my male. She's still got a few spots, but her color has come back to her and she's eating again and swimming around normally. Now that her fins aren't clamped, I noticed a small hole in her dorsal fin! What does this mean? Does she have fin rot?? Can I mix Jungle Fungus Clear and Hex-a-Mit to treat it? There isn't anything in the tank to poke a hole like that, just a rock that isn't sharp, smooth gravel and the heater. HELP!
