Thanks! I was worried, I’ll keep an eye out for morecould be a leech, could be tubifex, or a nematode. i'd take it out and look for more. leeches will be stuck to the snails, tubifex will make little tan colored tubes on things, and nematodes just swim around. the only one of those that really does harm is a leech.
Haha, yeah. It can be scary sometimes. I have tubifex worms, flat worms, copepods, snails, shrimp...all living harmoniously. All are harmless in my tank (except the darn bladder snails Im constantly crushing). You have to watch out for the bad ones though. That guy you found doesnt look like a bad guy but I would take him out anyway. He could compete for food. I have that issue with my flatworms, which is why I remove them when I can.I’ve honestly never seen anything that I haven’t purposely put in a tank before.
