Is this loach eggs?

[ugn]

I measured my PH, in my 240L tank and found out that is was 4,5 (!) so i decided in panic to change some water.
When I was done with this i decided to clean my filter house and noticed some small bubbles. I was curious and tryed to lift one up.. i could, it didn't burst.





Could this be loach eggs? Look at the size, it's very different..
But i decided to move them over in a breeding box just to monitor them..

What kind of loaches as well as other fish you have in this tank?

I have:
2 clown loaches - ~3-4 years old
6 Siamese algae-eater - about same age
10 Corydoras Panda - ~small, half a year old

That's it.
