Micro organisms. ID needed

Hi!
I never got something like any of my tanks, now I'm curious are they any good
for fish as food in the tank? Can they cause issues and harm? What are they?

Any info appreciated
Thanks

My guess:

picture one cyclops http://en.wikipedia.org/wiki/Cyclops_(genus)
picture two Planaria http://en.wikipedia.org/wiki/Planarian

Free fish food! Really nice clear pictures of them.

I agree about the Cyclops but fish don't eat planaria. If they ever try they'd spit it out. I think it isn't tasty but I am yet to try it myself Planaria is a carnivorous pest and can be dangerous to small fry or shrimp. It normally gets introduced via plants and such, it isn't caused by overfeeding but it will feed nicely on fish food and small live stuff if big enough.

My old goldfish used to love eating them, then again, he used to eat everything and anything. These tropical fish must be fussy.

Thanks for info.
So i don't care about no1. But I need to think how to get rid of no2. Ugly worms.

To be honest, looking at the pictures I am not even certain it's planaria on nr2. Planaria's head has an arrow shape. Have a look on google pictures and see if it looks like them. If not, it could be a harmless detritus worm of some sort.
If it is planaria, best to get rid of it.

Wow, that sounds interesting. Do you know if there are instructions somewhere on how to do this?

 

[Lauris]

Heh. You can try google. But my instructions are simply enough - get two the same diameter lenses and stick them somehow together in reverse. I used rubber bands. Other thing you might need is tripod. And camera with great iso quality. These pics are taken with 8000-12000 iso.

 

[Mr. Teapot]

Thanks Lauris, sounds simple enough. Can't wait to give it try,!

You can get reversing rings to join the two lenses together for £1- try ebay or suntekstore.

 

[Lauris]

Yep. That's a more proper solution. I just dont have any and diy'ed with rubber bands
