Best geo for "earth eating"?

  • We are currently upgrading MFK. thanks! -neo
If you are putting Geos with a larger or more aggressive fish, go with larger, more aggressive Geos. G. altifrons fit the bill. Most LFS will carry them as "G. surinamensis." They are one of the most common geos out there. I see them at places like Pet Supermarket all the time. A lot of mom and pop stores can get them (they are usually on lists from the big distributors like Segrest Farms) but you may have to ask them specifically to bring them in. A group of six would be good.

The one problem I see is that a group of fish that have the potential to grow 10"+ and aggressive may be cramped in a 125 with tankmates. Orange heads are beautiful but they are also on the smaller side (8" max with extremely ideal conditions, but more like 4 - 6") and fairly placid. I've never had dats, but if they're aggressive they may push the orange heads around.

I've kept several species now including G. winemilleri and G. brachybranchus, which both grow pretty large, and they really only sift maybe the top 1/2" - 1" of sand, max. If you're just looking for something to sift out uneaten food and keep algae from growing on the top layer of sand then they're probably fine. If you're expecting them to eat detritus or sift a deep sand bed to prevent things like gas pockets from forming, no species that I know of really fits that bill. I still have to do that manually with a long-handled algae brush or piece of PVC.
 
Geos are a great additon to my small cichla. They sift the sand quite well. I started out w/ a couple altifrons and juraparis. The altifrons have gorgeous colors and nice long streamers. Their colors rival that of a sw fish. Color crayon like. Well this dipped my liking for geos a bit more. I got a small group of balzani's. These guys have cool gold but an attitude to match that striking color. Tommorow I have a winnamilleri coming. I got bit by the geo bug ;)

I think I too have the geo bug. I am absolutely loving my red heads and have been looking at other geos for future tanks. I am also cleaning out some of my tank stocks and thinking about what geos I could get to fit in them. LOL

Just thought that I would add that some of the geos, specifically some from the Satanoperca genus such as leucosticta, are typically not found in "groups" in the wild. At best "pairs" have been seen during breeding season, otherwise they tend to swim solo. A common misconception in this hobby is that all geos are best kept in captivity in groups.

I would also not keep red/orange heads with dats due to dats size and aggro levels.
 
Thank you Neil. So it sounds like I'll be buying a few more Heckelii to grow out with the one I already have and buying some Altifrons to grow out for the "dat" tank

Strollo winnamilleri also get quite large. Snookn21 has some killer prices on some lg wins as well. Mine should get here this afternoon ;)
 
I have 6 Red Heads in my 225. I bought them at about and inch tiny little guys. This was about 2.5 years ago I think the bigest male is about 7" the smallest female is about 5" maybe a little bigger. My fish grew very slowly, but there beauty is amazing. I feed mine NLS 1mm pellets and doubt they would do well as a clean up crew these eat a lot and are constantly sifting thru the sand. I have about 10 Emerald Corys that get clean up duty, but I don't have large aggro fish in this tank either. I'm far from an expert on the rest of the Geo. species.
