Hey there folks, I need help identifying this to either cure it or identify it as a non-problem.

I've recently noticed these little white spots showing up all over my artificial rock wall. They're maybe half the size of a grain of rice and of similar shape.

I recently added 10 plant-friendly, algae eating snails which seem to be doing a fantastic job clearing the rock wall of algae. Are the white spots snail poop perhaps?

The fish don't don't seem to be showing any symptoms yet. Everyone appears healthy.

The only point of maintenance that tends to go neglected is that I don't vacuum the sand as frequently as I should since it requires a step-ladder, moving aquatic plants around, etc.



Other then that, this is a 1yr old, established 110gal tall aquarium, fresh water, excellent water quality, UV filter, and a custom over-sized mech / bio filter. I also keep some live plants in there and added a few around the same time as the snails. I have all manner of incompatible fish that do seem to get along fine. Stock list as follows:

10 snails
3 pearl gouramis
6 mollys, give or take a few... (been a while since I counted.)
2 guppies
2 silver dollars
1 coryadora catfish
1 someotherkinda catfish
5 tiger barbs
1 black ghost knife (several years old, 10"+)
1 cichlid, blue-regal or something like that
 
1 someotherkinda catfish....rare, very rare indeed:ROFL::ROFL:
 
sorry all laughs aside, pics put some up to help identification
