Is it safe? I also have some Inca snails and large fancy goldfish in the same tank. They do not pick up and spit out the current gravel like past ones I had, but I imagine they will pick up some when feeding. Will this sand harm them in any way or is it safe. When I searched this question regarding loaches I found answers both ways whether it was safe or not. Does anyone have experience with this substrate and loaches/snails/goldfish? Thank you for reading.
