Best Color of Gravel?

[SalviniCichlidFan]

What's the best color gravel to make the fishes in my list's colors "pop"?

I currently have
Green terror
Firemouth
Jewel
Blood Parrot
Black convict
OB Peacock
Orange Peacock
Dragon Blood Peacock
Yellow Lab
Black haplochromis

edit: It would be most helpful if you format your response like this,

Green terror - insert gravel olor
Firemouth - insert gravel color
etc.

Usually darker gravels and backgrounds are the best for popping colors across the board.

is there a way to change gravel in a tank without disturbing the cycle and equilibrium of the tank?

Depends on how established the filter is and such.
I once changed all gravel and decor with no problems at all. Just was a real pain to accomplish.

When I did it
Take water level down to 3in above the height of the existing substrate
Scoop out old substrate
Add in new pre washed substrate
Refill as normal
Feed lightly for a few weeks as the new substrate gets colonized, up the water changes as well.

Leaving some water in the tank let's some beneficial bacteria disturbed from the old substrate settle into the new.

Over the years,I have used light sand, natural gravel, and black sand. My favorite is the black sand.

My mom used to have this Gravel in the 40g I gave her and to this day there’s still remnants of green and purple hidden in the river pebbles.
