I had this same debate. Exact same situation, actually, except I had 2
smaller tanks and was trying to figure out how I wanted my 90g tank set up.
I ended up deciding on sand. Concrete sand, to be exact. It is a substrate
which the fish can still dig/play in, but it doesn't house food particles
like gravel can since they have no where to hide. The sand packs right
down. You may be surprised at how many people do this.
It does take alot of work to clean it. You have to put a little at a time
in a smaller bucket, fill with water and stir up, then drain off water and
repeat. This gets rid of any small dust particles, and anything else which
may be in the sand (I found leaf bits and a few small twigs). Then dry it
in the hot sun.
GF have been known to choke on gravel bits, which is what worried me. It's
never happened to me personally, but I have heard of it. I have rocks and
plastic plants in the sand now, and plan to add some real plants as well,
someday. I have 4 mystery snails, one swordtail and my GF in the tank.
It's just an option to look into. I don't suggest you get dyed sand since
the chemicals would probably be deadly to your GF. I have heard of using
vegetable dyes to color it, which you can try if you are that patient, which
I am not LOL. You can purchase colored sand substrate (try
www.mops.com).
I got mine left over from when we had the chimney fixed a few months ago. I
don't suggest you use "brick sand" since it is too fine, but concrete sand
is a little more coarse, yet is soft enough for the fish. Good luck.
