As I mentioned, I
finally got some plants that are growing well and are too tough to be
ripped
up by the fish, which cuts down on the frequency of water changes by
removing nitrates. So my tank looks natural and the water stays good with
very little tank maintenance. But the fish are getting big and if they
end
up choking on gravel it's no good.

I think bigger rocks instead of or on top of a thin layer of gravel may be
a
solution.

Thanks for any input or experience with this problem.


In my barebottom goldfish tank I have a selection of plants attached to
driftwood.
I tried plants in clay pots, plants attached to rocks, and this works much
better. They are so lightweight that I can scoot them around with the siphon
while vacuuming and not worry that they will tip over and crack my glass.
This always bugged me with the pots and rocks- one slip of the grip and
*crash*.
