JaredL Posted April 1 Share Posted April 1 Anybody seen this before? 29gal over 5 years old. Well planted and stable. Canister filter. Fish all happy. Sticks to the glass. Doesn't move so I don't think it's some type of microfauna. I'm familiar with the film you can get with still water, but I have alot of surface agitation as my outlet is pointed at the surface. Let me know if you have questions. Link to comment Share on other sites More sharing options...
mynameisnobody Posted April 1 Share Posted April 1 Im not 100% sure but that looks like insect eggs to me. 1 Link to comment Share on other sites More sharing options...
JaredL Posted April 2 Author Share Posted April 2 @mynameisnobody Thanks for the feedback. Seems like way too much to be insect eggs to me. I haven't noticed any bugs flying around. Really need to get that microscope I'm always saying I'll buy. 1 Link to comment Share on other sites More sharing options...

Add to that, if was insect eggs, the fish would be gorging themselves. Eggs are delicious and nutritious 2 Link to comment Share on other sites More sharing options...
EggShappedFish Posted April 2 Share Posted April 2 That is interesting! To me it looks like something that has dropped from outside. Like dust or pollen 2 Link to comment Share on other sites More sharing options...
Tony s Posted April 2 Share Posted April 2 Question, do you use anything like purigen in your canister? I had a bag start leaking on me. Did not notice the top as mine has a hood. But the sides collected fine granular particles. Still cleaning them up 1 Link to comment Share on other sites More sharing options...
JaredL Posted April 2 Author Share Posted April 2 @Tony s I don't use any purigen. Just coarse sponge and fine filter material, with a coarse pre-filter on intake. But that does make me think that possibly my filter is clogged and maybe just bypassing the filter media now. 1 Link to comment Share on other sites More sharing options...
Tony s Posted April 2 Share Posted April 2 If cleaning the filter doesn’t work. You could use a clean paper towel and lay it on the surface. That would remove it temporarily. If it comes back. I’d look for something degrading. Possibly even the filter itself. Or a piece of decor another question. When you smush it between your fingers. Does it stay hard or smear into your fingers. If it stays hard. May be decor. Doesn’t sound organic at that point 1 Link to comment Share on other sites More sharing options...
Biotope Biologist Posted April 2 Share Posted April 2 I’ve seen algae do this from time to time or as said before could be pollen, but it looks like the tank is normally sealed off with a lid so id say a type of brown algae most likely 3 Link to comment Share on other sites More sharing options...
JaredL Posted April 2 Author Share Posted April 2 @Tony s It squishes. No artificial decor in the tank, just an old piece of driftwood. Did a 20% water change today to see if it chanhes. If not I might reluctantly dig into the canister filter and see what I find. @Biotope Biologist Thanks. I'm leaning towards a type of algae or organic also as it's only on the surface. Everybody seems happy and healthy so I may just wait and see. Curious to see how the mystery progresses. Link to comment Share on other sites More sharing options...
