I've been investigating an unexplained fish death and I noticed something I have never noticed before. Very close inspection has revealed thousands of very very tiny somethings adhering to the inside of the glass on all sides. Invisible unless you are right up within a couple inches of the glass. They are round, whitish, translucent, and about 1/2mm in size. They wave gently in the current. They are everywhere. Not sure if this is a threat. Anyone know what they could be? They are far too small to photograph, unfortunately. Hopefully, this is just a strange-looking algae bloom, or a normal microflora/fauna, but I just don't know. Any input would be appreciated. Thanks I really don't want to lose any more juvenile angelfish!

Is this a freshwater tank or a salt water tank? Duh...didn't read the part about the angelfish

Could they be copepods or hydra?

Sorry. 60 gallon freshwater. Parameters: 0,0,10-20. Ph 7.8 temperature 79 degrees F. Tank is cycled and has been running 2 1/2 months. I'll look up copepods and hydra, thanks!

No. As far as I can tell, they don't really look like little bugs, or hydra. They look like bubbles sort of, but they are certainly organic and fleshy.

is it slime starting maybe?
Thank you, but I don't think so.

Look through these:
Thanks for the link! Nothing on that page matches, but I'll look through some of the other articles on that site.

I looked with a magnifying glass. They appear to be some kind of sac-like structure, anchored to the glass, soft and fleshy and almost transparent. Most or maybe even all look ruptured. Like a hatched snail egg. But I have no snails and there are thousands. Interestingly, they cannot be found on any other surfaces, such as plants, decorations, heater etc. Just on the glass. They wipe right off. The angels may be eating them, it's hard to say for sure. I'm trying to host a full-rez of a photo I took. You can't really see them well in the photo, but can't hurt, right? Let me figure out how to post a link to it when I get it uploaded somewhere...

I'd be interested in trying to see what they look like! Are you sure they aren't snail eggs?

Lets see if this works. If it does, the "invaders" are the small gray spots visible against the top part of the rock decoration.

I have no idea why the thumbnail is not a link. Nor why it posted itself 3 times. Sorry all.

The is too small (at least for me...), try uploading it to your fishlore gallery and then sending us a link to it.

Yeah, snail eggs are a very remote possibility. While there are no snails that I know of in the tank, a few weeks ago I squeezed some sponge filter media from my awesome LFS into a bag to seed my filters with beneficial bacteria. Cycled the tank very quickly. Conceivably, snail eggs could come from that. But this many? And that's only if there were snails in that tank. I'd think you would need adult snails in my tank to distribute thousands of eggs all over the place. And they're all hatched apparently, if they are eggs, so I'd be seeing snails somewhere by now, right? Thanks for all the suggestions everybody! I do appreciate your time and help.

Limpets. Looked them up on google s. Probably not. These things cannot move independently. I'm thinking eggs of some sort. Maybe the zebra danios spawned before I re-homed them? I have no clue what that would look like.

Copepods look like bugs, though. Nothing like that here. Hopefully it's just some harmless microzoa

Roughly a week ago. Too many eggs for danio spawn, and they wouldn't be stuck to the sides. Well, thank you everyone for your insight. Looks like a mystery, my internet searches are not turning much up. The angelfish are snacking on these things whatever they are. Let's just hope it's not related to the fish death. The 3 remaining angels are by all appearances thriving. I'm going to scrape these sacs off and keep a close eye on things. Thanks again!

Yeah, I think they would have hatched by now... Hopefully it's nothing nasty If you ever figure out what it is let us know!
