Some sort of algae/unknown growth

[illusion54]

I have a 29 gallon, planted, tank and ive noticed this in the past, but recently it has been getting more noticable.

The problem is, on the sides of my glass, there are small little things hanging off the sides of the glass. They dont have any coloration and do not clump together. There are hundreds of them, none no bigger than a mm in diameter.

Anyone know what exactly it is?

Thanks,
Mitch

Do they look like this

if so then they are Hydra, a type of freshwater anemone.

The pic is from my tank, cycling at the moment but hopefully will become fish food soon.

i've had those in my tank once
i reduced feeding a whole lot and they're gone now

most fish and snails will eat them though, but it is a sign of overfeeding most of the time

awesome close-up benzonar!!!
