White sand will only bleach out your bichirs except ornates. If you wanna get black sand, get Tahitian moon sand. Many people are using them and it never harms their fish. I've used it too in the past.iLoveHebe;2694975; said:ima get red/orange or white b/c black has iron in it =(

I think you might need 40-50lbs of sand for 48x20x24.
