While looking at a group of daffodil fry I noticed a small worm swimming in the tank. Have not seen it before, and only have trouble with one new fish, I assume stress related. I would like to find an online reference to identify the critter before I nuke the tank only to find it harmless

Well, it could be hydra or planaria, which are harmless. Usually, you can control this simply by cutting back on feeding and increasing the frequency of your water changes. :thumb:

Thank you from what i read on the forum I thought that might be the case. I would still like to get some resource material on parasites/illness if you have a good source.
