Is sand an Absolute must with Geos?

[RD.]

Personally I think that the geo fanatics are missing the bigger picture;

I would be worried about the P-Bass beating the heck out of the geos, they are pretty mellow fish.

Agreed.

Keeping geos in a tank with gravel for a few weeks is a non issue, the aggression from a group of pbass would be a far greater concern IMO.
Personally I would hold off on the geos until you have the new tank set up & water quality in check, then add the geos, and once they have fully acclimatized to their new surroundings only then introduce the pbass to the tank.

I have PFS in my 180...200 pounds of it My geos are very happy to suck it up and spit it out all day long

Good point.

Also wanted to say that Geos are not bottom cleaners. If you are looking for something that functions like some catfish, Geos are not a good choice.
