This probably doesn't have a right or wrong answer but I'm looking for opinions. I recently acquired a couple of different geo species and i've noticed some "eat earth" more actively than others. Is there one species that does a better job at cleaning?

There probably are some that are more active due to either tank parameters (higher temps for fish that are use to colder water will boost their metabolism more than others that are use to higher temps, and a higher metabolism will make a fish more active) or size (some smaller geo will move faster than larger geo, but their smaller size makes them look like they are doing more when really a larger geo's mouth will do more work).

I personally think getting a good number of geo's based on tank size will do all the work you need/want. For instance, I just added six 2.5" red head geo's to my 125 and they will eventually be the perfect size sand sifter for my tank size while larger tanks could use larger geos like altifrons or brasilensis.

Geos require groups of at least 4 and with the smallest species of geo (not counting gymnos) reaching 6" on average, no one would recommend a tank smaller than a 90 gallon.

I think my mistake is that I have 1 of each species, 3 total. 2 smaller in my 55 and 1 big one in my 125. They're so expensive as they get bigger. I guess the other question is if there a species that grows faster than others

Aggression wouldn't be my issue since they would be going in my datnoid tank. They just need to be big enough to not get eaten. Perhaps I 'll
Pick up 4 or 5 altifrons to grow out.

No best. They are all slow growers. Of course larger species take longer to reach ultimate size than smaller species do.

I have heard mixed views on different species of geo's being kept in low species numbers, but higher geo numbers (i.e. 5 geos of differing species kept together). I am of the opinion that same species need to be kept in groups of 4+.

Out of curiosity, what species do you have? If you have a favorite species, you might think of getting rid of the other two in favor of three more of the favorite species.
