Please read post and see links planaria commonly missidentified

Planaria are usually on the glass, it's stylaria that swim in an "s" wiggle. Both are a sign of overfeeding, lack of filter or substrate cleaning etc but not really harmful.

Sokoly, with the amount you feed you may need to do cleaning & maintenance more frequently. On my discus tank I use prefilters to keep "bits" out of the filter & rinse them every day or 2. It's also bare bottom so nothing gets trapped in substrate. I had a thin layer of sand but bare is so much easier. I do a water change 30-50% daily for my juvies.
 
Dear fishorama, please take a look at my gallery fotos and my tank. Use to have some algae problems earlier but after setting up a UV steriliser and Einchornia floating plants the problems were solved. Probably when I introduced the watter lily I have introduced some of the stylaria?
What do you suggest how do I get rid of them? My tank is 600litars and has 6 wild caught red spotted discus. I really take care not a drop of food stays uneaten and have few Corydoras sterbae, one L134 (peckolita)and two ancistrus. Soem Cardinal tetras also.
I run an Eheim 2400l/h with an active surface of 20 liter filter media.
I almost never touch the substrate since it is out of 2-3mm quarz and is hard to syphone such a tiny substrate.
Do you suggest less feeding?
 
Your fish look like adults? Very nice! I have sand & hold a small vacuum ~an inch above the sand. I sort of swirl the end to kick up any poo etc so the syphon can get it. I lose a tiny bit of sand sometimes, practice helps.

Stylaria aren't a big deal, some fish may eat them. How often do you rinse out your filter media (intank or dechlorinated water), they can live there too. I'm new to discus but I think 3 or 4 meals is good for adults. I feed juveniles 5-7 meals & need to clean every day.
 
My little ten gallon had both the squiggly free swimming guys and the dudes that hung on the glass...never knew what they were until now. It's funny though, ya'll say they come in great numbers when there is a lot of detritus in the gravel, but my tank housed a single betta, who sadly at the time these things popped up had become ill and lost it's will and strength to eat (he died on Sunday :( ), so there wasn't much detritus in the gravel. I cleaned the tank which did have a bit of an algae issue, the little wormies did seem to be eating that, so probably that's how they came to become so numerous, but the gravel hardly had any detritus in it. Oh well, fishy died, tank has been taken down and will be stored away until I get enough money saved up to turn it into a mini reef. The only thing I can think of as to how they got in there is my using the glass scrubber in my other tank which has live plants, and all sort of buggies come on plants, and transferred the critters when I used the scrubber in the ten gallon. I don't see the wormies in the big tank, but there are more fish and they probably eat them, whereas the betta was alone, sick and not eating, and the numbers grew.
 
I just call em dirty water worms. Day after stirrin up gravel with vac I find lots climbing up the glass, Gourami and killi fry eat em and they retreat down into the gravel durring the day. I mostly just have the glass clinging ones. I know I over feed with cheap flake but oh well just means I do more water changes. Thanks for the info and the pics helped me clear somethings up and confirm what I figured
 
Good bump. I think when most people think they have planaria, they really have stylaria. I've found most tetras will gorge themselves on stylaria given a chance. I know I had a bad outbreak and when I started cleaning both the neons and the glolight tets were following the gravel vac around the tank and darting at every "squiggle" they could find. It was fairly interesting...if the worm didn't move, there was a fair chance he could make it back to the bottom, but once it did the tiniest "squig" he was as good as dead.
 
Thanks for bring this up. I also thought they were planaria. I've seen only two or three of the white sqiggly things after vacuuming in my frog/betta tank and got one on video. The tank is well filtered and kept pretty clean, but I stepped up maintenance to twice weekly and haven't seen any since.
