Alright, so I have noticed that a lot of the fish I would like to include in my new set up prefer dark sand substrate (for example, kuhli loaches). I can find dark, 1/8in gravel for a reasonable price, and I can find lighter colored sand substrate for a very reasonable price, but I can't find any dark sand substrate locally for less than $1 per lb, and I want about 100-150 lbs, so it's more than I'd like to pay. So...
A.) Is the dark, finer gravel going to be okay? It is more grey than black.
B.) Could regular sand substrate be acceptable if there is plenty of decor and hiding places to darken up the bottom?
C.) Do I absolutely need to save up the money for dark sand substrate before looking into these species?
I would like to provide a suitable habitat for the fish I am keeping, I'm just wondering whether there may be an acceptable compromise.
