Hi, everyone
I have set a new apisto tank last two weeks.
so, there is no fish.
Today I found some very small white tread like animal in my new tank.
It seems small earthworm or a kind of parasites?
A video clip file has been attached.

Hi all,
Looks like a Planaria.

If it is it will glide along the glass and have a V shaped head, with 2 very small black eyes. They are scavengers and they aren't a problem in Apisto. tanks, but they will eat the eggs of egg scatterers. I usually have some in the all the tanks and ignore them.

If you want to get rid of them there is a good article here: <http://www.planetinverts.com/killing_planaria_and_hydra.html>.
