It's probbaly best not to risk it. There could be chemeicals in them that are dangerous to your fish. If you are looking for colorful Petco, Petsmart and Walmart (In the fish section.) All have brightly colored gravel and decro. I beleive that some Petco's have colored sand to.
I wouldn't buy an colored sand, even if it's from PetCo. Same with gravel.
The problem is that they will usually leech out, you might not see it but as time goes by you'll notice the more duller and pale the color of the sand/gravel becomes. If you want sand go with Quikrete Playsand, many people on this forum use it.
Quikrete playsand? Hmm. I'll have to see if I can find it.
I'm converting all of my tanks to natural planted and using soil, and wanted some pretty sand to top it off with, lol. XD if nothing else, I'll just drop a couple of decorative stones in it. ^.^"
It's made of silica... Wouldn't that be harmful to a fish? o.0

I have seen on other fish forums that Crayola does say this sand is OK for fish tanks, that it's non toxic and does not leech colors or chemicals (because there are none). Many have used it in tanks. Let me find a quote...
Absolutely no chemicals are used in washing! Sand is washed in extremely hot water. Unlike some sand companies – No anti-fungal materials are placed in the sand. Before bagging – Crayola PlaySand is run through a rare earth magnet to make sure there is no metal in the sand. Then run through a Sweco screen to remove any possible foreign material that may have contaminated the sand during transportation. This is done to ensure a safe contaminant free sand!
before entering our production line. From that point it directly enters the coloring/coating process where it passes through a continuous “tube” of pigment. (If by some chance a fungus or bio-material survived that process it then would immediately enter a dryer that heats the sand to 250 degrees.)
Designed to be submerged 100% in water without color fade or bleed
Our quartz sand resists abrasion better than typical sands. Each grain of sanded has been screened and is completely round – giving it a smooth sugary soft feel
I am Alicia Lewis, Crayola PlaySand Specialist. I was received a request to post on this forum to put a few of you guys at ease. I'm glad to see our website was quoted several times for safety, and I just wanted to take a moment to add.
We have been creating Crayola PlaySand for over 3 years - and we get about 50-100 animal/fish safety questions a month. To date - Not a single animal - fish or furry has been reported to be harmed, sick or ill... Though we've gotten alot of interesting breeding stories!
The sand is perfectly rounded, so no sharp edges (thus no dust either). As you read - non-toxic, but also lead free. The colorant is bonded to the sand at 250 degrees, and also the colorant is environmentally friendly. As a matter of fact we don't even use chemicals in our cleaning process - it undergoes an extremley hot water wash.
Like all Crayola products, we don't do any animal testing. I can simply assure you that I've have fish swimming in blue and green sand in my office since 2008, and they are the same fish.
We invite all inquiries, questions, pictures. Thank you.
