So, I was cleaning out my cichlid fry tank and found this worm. Please let me know your opinion on what kind it is: 1. Leftover from feeding black worms a couple months ago (although it is lighter). I did notice that some would get under decorations and still alive for several weeks after feeding when I vacuumed. I moved a couple pieces of deco from main tanks to fry tank. 2. Somehow got a bot fly worm 3. Internal parasite released by the mother fish before I pulled her from fry tank 4. Other? No signs of parasites in adult fish. No flashing, lack of appetite, off color, etc. I treat all new fish with levimasole during a 40 day quarantine due to a camallanus infestation a few years ago. I am super paranoid since then so this has me a little freaked out. The thought of treating all my tanks with levimasole at the same time is overwhelming.
