Last month, I stated noticing, that there were, a few purple or lavender splotches on the glass, in my rescue tank. Now there are close to 50 to a 75 of them.
Is this some sort of algae, Coraline or not?
Just prior to the splotches appearance, I noticed, a tiny lavender squiggly worm-like creatures, whipping through the water. Then resting on the glass, I just thought they had died and that was just their remains. But now, I see an explosion of these splotches, all over any smooth glass surface area.
What could they be? And is that a good or bad sign?
Tank Param's:
Amon 0.00

Here's the best two photo's I have.
Don't mind the Nerite Snail cleaning the glass!
Thanks in advance for any identification, hints, answers or advice!
