Black petco sand for m-motoro

[freshfishin727]

I have a 6.5x2.5×2.5 tank that is stocked with
5 red hooks
2 lapradei
1 endlicheri
2 tarpon
1 african pike
1 african arowana
1 lima shovel
And now a newly added 10" disc male marbled ray.

Question the tank has 1.5 deep black petco sand on the bottom, bout 6 months old. No issues on the bichirs but does this sand qualify for a fwray

Yes it will be great for the ray! I've seen petco black sand. As long is its fine and no edges your good. Post pics of your tank!
