I appologise in advance for the poor quality pic. My husband has my tripod mount in his bag and I forgot to get it out this morning.


thats some of the stuff on my free floating thermometer

I know the first response will be it looks like snail eggs. It isn't, I can assure you that. The only snails in this tank are trumpet snails.

Also snail eggs don't wiggle and wave in the current. It doesn't appear to be a new hydra outbreak, it looks very different. Not sure what other jelly like animals there are. it seems to be in colonies, small groups getting larger over time. And actually quite fast. I noticed a jelly mass yesterday and there appear to be several more scattered around.

Could these be a different sort of animal? Bacteria infection? Algae?

they appear to be small white-transparent ball like things that wiggle and flutter in the glass.

A "jelly-like" mass suggests eggs of some kind, but the photos don't look like eggs, except for maybe one mass. Perhaps whatever was in the mass has hatched and what is left is disintegrating?

What animals are in your tank?

Is it possible that some flying insect could have deposited them and left?

Your micro-photographs are quite good, BTW.

Shrimp and only shrimp. Possible to the flying insect. we did have a huge mass of gnats recently that inundated my appartment.

It could be gnat (aka midge) eggs. Many species of these lay their eggs in the water, where some hatch into the larvae that we buy for fish food, called "bloodworms."

If that's what they are, you should see small red worm-like creatures swimming in an "s" motion in a few weeks.

I would also guess they're some sort of egg case/sac from some sort of insect. If they do turn out to be bloodworms, I'm not sure the shrimp will eat them, but if you have any tanks with fish, they will quickly devour them.

My guess is that these are colonies of some sort of protozoan that feeds on bacteria in the water. Some Vorticella species can make large colonies that look like what is in your picture.

I drew this ... to sort of help show what it looks like close up. Anyway, what sort of control is there for something like that? Water changes obviously.



Edit: I did an 80% waterchange. I will do another 50% tomorrow. I am using some water from the other tanks as well so I can keep the benefical bacteria in.

How did we get from the pictures of what looked like egg sacs to that creature that looks like a protozoa of some kind? Did the sacs hatch?

Maybe you are worrying too much about this. Any healthy aquarium has many tiny creatures that serve useful functions.

Why not sit back and wait to see what happens. particularly with the shrimp that has a passenger?

I don't think its egg sacks. Not the way it spreads into big gelatnious blobs. I haven't seen anything either. I'm going to watch the passenger shrimp, but it does concern me. I spent about 50$ on the shrimp in that tank and I don't want them keeling over.
