Hi Ive got this garnet sand, and want to know if it is safe for panda corys and pigmys, its like dust, the sand really size is 110-140 times smaller than the pic


the photos were taken with 110-140x(combining zoon and loupes)

Its hard to tell, but at least some of it looks like it has rounded edges. Try rubbing some in your palms and see how it feels.

micro abrasive but les than beach sand or silica sand

I'd give it a go, but keep close close watch on barbels.

thank you, exactly how do eroded barbels look like?

Here are two examples from the Cat-eLog.

Oh I keep watching at them, Las afternoon I gave them the sand and some maple dry leaves they layd eggs under the leaves

I used to stock and use some garnet sand when I had a fish shop. Garnets and garnet sands are found and processed on an industrial scale in Northern Idaho about 130 miles from where I live. They also find gem quality garnets. Garnet is the state rock of Idaho.
It is about the same as quartz and black "moon" sand as far as particle shapes and sharpness but garnet is harder and much denser than quartz and black sand. I don't remember having any problems with Corydoras kept on garnet sand but it is so dense and fine that plants did not thrive in it.

thank you very mutch!
