What’s growing on my glass??

[Phillip]

I have these worn looking things growing on the side of one of my tanks. Any idea what they are? Should I be worried?? It won’t let me post a video here, but they are wiggling around.

Those are Rhabdocoela, a type of flatworm. They do crop up and are generally harmless. If you get too many it could be from overfeeding.

Thanks. I definitely did overfeed for a while. Since I reduced feeding will they go away on their own, or do I need to treat the with something?

Reducing feeding will reduce the population, it won'te completely remove them. I wouldn't worry too much about them. Gravel vaccing also will remove the ones hidden in your substrate.

Gotcha. Thanks for the help!!

I think more unsightly and not harmful at all.  I believe..

I'm seeing the flatworms already mentioned, but are there also skinny long white worms I'm seeing? If so, you could have detritus worms as well. Harmless to tank inhabitants as well, and will be reduced by feeding less and gravel vacuuming.

Thanks. I was feeding a little more than normal and I guess it got out of hand.
