I've been keeping a 10 gallon aquarium since last fall, and this week clear balls about 1/2-3/4" around started showing up. One day there was one, then four, and today there are about eight. I picked one of them up, and it's not slimy, and it feels somewhat solid (I didn't try to squash it, though).
I have a big snail (and tons of little ones), ghost shrimp (some carrying eggs), a paradise fish, two zebra danios (one of them is gravid), a platy, and a paradise fish in there. Any ideas? I've been doing bi-weekly cleaning by changing 1/3 of the water (replacing with RO
), and vacuuming the gravel ... I'm guessing they're not eggs, since they're so big in comparison to the fish I have??? If not eggs, though, what are they?
(please see the attached picture ... I moved them to a separate container with an air pump in case they were for some reason either a danger to the fish in the aquarium, or in case they were in danger from the other fish.)
Thanks for your help in solving this mystery!
