Best substrate for goldfish?

Hi everyone, first time poster

I currently have aquarium rocks in my goldfish tank, which I now realise isnít the best idea as I read they can choke on them.

Can anyone advise me what is the best substrate for fancy goldfish? I want it to be black. I donít have real plants.

And any tips on how to change substrate with fish in the tank?

Thanks so much

How long have you had your tank set up? And what size is it? Yes indeed, the GF will easily get a mouth sized pebble in their mouth. I have had it happen when my pond was bare bottom. Though it happened. I bought a potted lily and set it on a side shelf and before too long one of them had snagged a stone the plant pot had one top to help weight it. I didn't even think of it being in there.

Many use a bare bottom tank, you can paint the underside of the tank, and add other plants, large decorative stones and smooth DW /driftwood. Easy to clean.

Sand is a very good substrate.
Favorite tank right now - 12G Edge nano fish

New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?

Larger stones that the fish can't eat would work, but I think that would present a cleaning challenge.

Sand works well and you can get it in different colors.
