Invert Identification

SinCrisis

Hey all, recently I went on vacation and came home to find that my snail had died. It was the only inhabitant in its 5 gallon acrylic tank. Upon inspecting the tank, i found that I had gained a bunch of new inverts and I have some idea of what some were and have no idea about others. I was wondering if anyone would be willing to help me identify them?

First there are these little worms taht ahve all gathered at the top of the tank, right under the waterline, I'm assuming they're planeria.

Second, there are these tiny round things, smaller than the planeria, that roam around a patch of algae. I do not know what these are. However, they are tiny and white and all of them are oval shaped. They sometimes get blown off the algae by the current.

A worm of some sort has moved into the algae patch also, there are small long areas where the worm has made a tube and it comes out to eat the algae periodically and when i tap the alcrylic they retreat deep into their tubes. They are brownish/tanish. The longest one is a little under a centimeter and very thin, like string.

MT snail, I swear there were none before I left but i saw one the other day, very tiny eating the algae.

Does anyone know what the small oval things are and what the worm is?

Also, no food has been added to the tank for over a month now, so the majority of the food for those inverts has been the algae patch. The only other plants in the tank is a Java Moss on wood and 2 bamboo stalks.

Can you post any clear photos of the inverts in question?

I can try but they're too small to see. These are all very tiny creatures, the worms are about as thick as a thread, like the thread you use to sow buttons onto shirts and the oval ones are just specs.

have you bought live plants recently? I know tubifex can survive in the substrate of an aquarium, but I wouldn't imagine you've been feeding a snail live tubifex worms. Maybe gnats or mosquitos laid eggs in your tank? They could be the ones under the waterline perhaps.

There used to be a Hornwort and miscroswords i got from petsmart but both died and were consumed by the snail. I looked up tubifex worms, these dont look like the kind that were on my tank, the ones on my tank made their won tunnels, like their own tubes and they stick their heads out, at least i think its their heads. Currently i dont see any of them anymore it seems they left their tubes. However the small oval creatures are still moving and im sure the worms at the waterline, i am sure are planeria.
