Only real thing of note for Oliver's tank is that I've seen these tiny things on the glass. They don't have the right shape for MTS and look like very tiny clear blobs with a dark center- which is a hard bit when I scrape them off w/my finger. I thought maybe just-hatched pond/bladder snails? A few weeks ago I did find another pond snail in here (thought I'd got them all, guess not). I squished it, but maybe it managed to lay eggs first, or I missed another one. I wanted to clean the front glass this week, so picked all these tiny things off with fingernails (tedious job) and put some under the microscope. But I must have crushed them when removing, it's a mess of tissue and a bit of blood and I have no idea what they are. There is a hard, shell part or carapace- I can see bits of it, so must be a snail I think.
(I just looked it up. Most snails' blood is blue. Ramshorns have red hemoglobin. So these could be tiny ramshorns...? or something else).
