I really don’t know if this is the right subforum for this, so feel free to move it.

I have a tank that had a catastrophic collapse. All fish died, a few inverts were still alive, but died off over time. There was one hermit crab that was alive, I assume (based on a google) that he lived out his life. This was over 2 years ago. It’s been sitting, just being topped off with RO water to keep the pump running, and nothing else done with it.

I decided to get it going again. I did not want to start over, so I’ve done a couple big water changes. Nitrates are through the roof. Even after those water changes, the Hanna high range checker is maxed out. I couldn’t find all the fish after they died, so this makes sense.

Here’s what’s throwing me. There’s something stuck to the glass in quite a few places (probably a couple hundred of these). It doesn’t seem to be living, but unless I actually scrape, it doesn’t come off the glass. I didn’t think to get a photo (I can try tonight), but it looks like a slug, or a snail without a shell. Except that the pointy end isn’t on the glass. Basically a squishy conical shape, stuck to the glass by the fat end. They’re maybe 1/3 of an inch long, and white-ish.

Any clue what these could be?
 
Hey, I got some photos. I know, I was not Johnny on the spot.

That’s what I thought they looked like. But how are they still alive? I definitely wouldn’t have neglected this tank like it was if I thought anything was alive in there. Can they survive basically liquid sodium nitrate? There were times I waited WAY too long to add RO/DI, so salinity would have been intermittently very high, as well. I just find it very surprising.
 
Some organisms can tolerate and even thrive in conditions where others would die. There’s probably all kinds of other life still in your tank.
