little white worms on tank glass?

They're probably just nematodes that hitched a ride on the plants. Nematodes are generally in the gravel/substrate, and when you do a water change or disturb the gravel, that's usually when you see them swimming around. They're a whitish color, look like a hair almost, swim in a S shape. When they get stuck on the glass above the water line, they just sit there, so that's probably what you're seeing.

Planaria is usually on the glass, but that looks like a white/grey colored slug, with an arrow shaped head.

Both are harmless to humans and the fish, but some forms of planaria will eat fish eggs/fry. No need to treat with a med, generally if you can see the parasite swimming around the tank, they're harmless otherwise they'd be attached to the fish. Do good gravel vacuums with your weekly water change, and don't overfeed. Eventually that'll starve them and they'll die off. Some fish will eat them as well.

If they were bad for the fish you never would have found them on the glass, they would be on the fish already!

Sometimes it's hard to know how things show up in our tanks, you just have to get rid of them when they do show up.

I wouldn't do any medicating, like I said, they would have been on the fish if they were parasites. There are lots of little creepy crawlies that are harmless.

My exboyfriend had a tank crammed with ciclids that grew to advance into crammed with those little worms. i spotted them at some point while the water grew to advance into stirred up. He advised me it grew to become into something from something he had fed them. i assumed it grew to become into freaky--they have been shifting on the interior the glass basically above the water interior the tank. i began out to ask your self whether they might pop out and advance right into a parasite on me! Eww. They have been form of sparkling, you may desire to extremely see them. i might sparkling your tank. yet, I doubt in the event that they are able to harm your fish. i could be prepared to guess that they are feeding on the different trash on your tank.

My brother just got his rayban sunglasses that he bought from this site last week.

Comes with box, looks good. Any way, it it worth buying.

They are harmless to your fish but are annoying as hell and are indicative of bad or high ammonia and nitrites in your tank for some period of time.

They feed of algae and waste on the bottom of your tank.

As your water parameters improve, you should be seeing less and less of them..

They are called "fry food". Without a pic, on balance they are unlikely to be a problem.
