worms swimming around!

  • We are currently upgrading MFK. thanks! -neo
I believe their some sort of planaria. Anyway, thats besides the fact. Theyre from overfeeding and left over food. I got them several years ago, just vaccume the sand or rock etc. Really clean the substrate and aquarium. Do a large waterchange of the same temp then slowly turn up the heat, 2 to 4 degrees. You may have to do another waterchange and vacuume a week or two later. They wont harm the fish, theyre just unsightful
 
It's unlikely your fish are in danger, IMO. Identifying them will depend on their habits and characteristics though. I had some odd swimming worms a while back when I took almost all the fish out. Turns out, a couple of fish, even guppies, would eat them all.
What do these worms do? Are they in the gravel, on the glass, free swimming? More details please :)
 
Theyre weird but really no problem. They last time i had them it was like 2 years ago in a divided 20 gallon betta tank. And yeah the fish will eat them lol. But again just the water changes, raise water temp 2 to 4 deg and add salt. Worms will be gone soon after. In the future, feed less and net leftovers
 
The worms are harmless, but it's a indication that there are leftovers and the tank is not in good shape. Just clean the tank a little, when feeding do so sparingly so that no leftovers remain. Any shouldbe netted out.

This can happen even in a new setup, the worms appear all of a sudden whenever leftovers remain in the tank. If you don't like the wriggling critters you can use Vermax which targets worms, or use copper safe (Mardel). I recently had this problem with a new setup and the only handy thing was Malachite green which I used. Thereafter the worms never appeared again.
 
Definately not anchor worms. As they "anchor". Anchor worms are also parasites, these little free swimming things just clean up excess leftovers. Easy to get rid of. I've never had to treat for anchor worms? How do you do that?
 
The way I've seen achor worms treated is by physically removing the worms with tweezers. Not sure if there's another way.
