White Worms Or Bugs On Filter?

I have a ten gallon tank that has been running with fish for a couple months. Yesterday I did a water change and afterwards I found these little white bugs/worms on my filter. They are only a few millimeters long, and I only see them on the back side of my filter. My RCS has been eating them or something near them. I was wondering if they are detritus worms or copepods, but I am too inexperienced to know.

What do you all think they are AND do I need to do anything about them? Thanks!!


Tank info:
0 ammonia
0 nitrites
0-.05 nitrates
6.5-7 PH (last test was 7)
60-120 GH (last test was 120)

Cleaning: I do a 30-40% water change weekly (using a gravel vac) including a weekly glass and filter cleaning (two filters, subversive and sponge)

 

That looks like flat worms.

 

They do not have triangular heads, not have I ever seen one swimming along the glass. Can they still be planaria? I read that if they stay low, close to the substrate then they are likely detritus worms. Either way I'd like to know if I need to do something about them.

 

I found it really disappointing to not hear anything else BUT for others with this issue here is what I think after doing lots of online research:

1.) It sounds like if someone has planaria they will KNOW they have it. And any other worm is likely not a problem but just a part of normal aquariums.

2.) My gourami ate all the worms or whatever they were. So yay! They are gone. I have not seen many more since. So even if you do not have anything that eats them, it may be possible to get them out with a turkey baster over the course of a couple days and that may be enough to keep the population smaller so you don't see them.

 

they look very similar to detritus worms to me. I wouldnt worry about it. espeially now that the fish ate themall haha

 

Well the only problem is if they're planaria they can be harmful to shrimp. I had some in my rcs only tank at one point and not all of them had an obvious triangular shaped head. I could only tell the shape of their head when they were on the move. Fish like to eat all these little aquarium bugs so they might help keep the population down.

1) Not necessarily as previously mentioned fish can eat them and less feeding keeps the population down.

2) If you needed or wanted to eradicate them, in lieu of a turkey baster I recommend treating with no planaria or fenbendazole. Remove the snails you want to keep though.
