The size ranges from sand grain size to very tiny pebble. Say pin head to small nail head size. Bigger than a salt grain, coarse sand size about. They don't cover the bottom, there are maybe 20 or so in there at any given time. They are heavy, the syphon won't pull them out very well. I have only glass and hard black river rock with a mostly bare bottomed tank, that's why they are so noticable. Fish pick them up and spit them back out, so they aren't edible.

I don't know if you saw my answer to your first question before it got pulled or not. But other than the long shot of teeth I'm at a loss.

How's the water quality in your area? What are the chances these are actually mineral deposits from hard water? The siphon would pull some of those out but it's impossible to get them all (believe me, I've tried). If that's what it is, you will also see signs of the same thing around your filters. In fact, this could be residue that broke off of the outside of your filter and fell into your tank.
I certainly hope that's what it is. Mystery substances in the tank are very stressful.

they are cleaning the tank and when they start pilling up gravel to one side look for bad weather, but should clean tank also.
