Geophagus altifrons + tetras, which species have worked for you?

  • We are currently upgrading MFK. thanks! -neo
Another thing i think would look awesome is a big group of hatchetfish. Theyre sout american and would look great with the size tank you have

Try some Bleeding Hearts if you can find them, they'll definitely get big enough.

Some of the species I've kept without issue;

Lemon Tetra
Rosy Tetra
Head-and-Taillight Tetra
Blue Emperor Tetra
Pristella Tetra
Bloodfin Tetra

Golden and Dwarf Pencilfish

Tried keeping Glowlight Tetra as well at one point but in my case they absolutely stressed out.

As I said in that linked thread, when I sold up one of my tanks my Lemon Tetra ended up in a tank with 10-12" G. altifrons (now classified as G. neambi) without issue.
 
I've had good luck keeping bleeding hearts and colombians with Geophagus and Satanoperca. Also while not really a tetra I suppose I've always liked to keep Hemiodus sp. with eartheaters.
 
Hey Ryan, good to see you're still lingering around! I'm going to have a look for bleeding hearts or lemons this weekend and will see how they go with my large altifrons, and maybe some Corydoras sterbai. Will get a small-ish group and see how they go before investing too much money.


mlancaster, interesting to see the barbs with geos, although that particular individual doesn't appear to have very long fins. Is that just the fish, or to do with the tankmates?! I loved the spotted metynnis I had years ago, and would have another school in a heartbeat apart from the fact that they decimated the geos fins in under a week...
 
I have a shoal of lemon tetra with my altifrons and satanoperca with no issues at all. I have even had half inch sajica fry in the tank without any issues, although they are only 6.5 - 7.5 inch in size so may not be the case long term!!

Hi David R,

Due to tank downsizing, that Geo was also in with a large tinfoil barb, which it constantly sparred with; therefore, it is hard to say if the smaller barbs were pecking at the trailers or if it was from the aggressive battles with the tinfoil barb. Either way it was not an ideal situation to add the Geo to the barb tank. The Geo did have trailers when it was younger and in a more peaceful South American community tank.

Back to your original question, this Geo was quite aggressive and would eat/attack smaller tetras and live-bearers (even sword-tails); the skirt tetras worked well because they would turn side ways and appear larger and harder to attack.

Thanks,
Matt
 
Cheers Thomas, as I recall that little balzanii was pretty small. I wonder if a young cichlid which spends more time hanging around the lower levels and sitting still than a tetra of the same size would have more chance of being eaten? Anyway, I picked up 20 lemon tetras yesterday from HFF (along with 20 sterbai corys, four festivum and six striped angels from Ron and Pupuke) so we'll see what happens once they've had a couple of weeks in the quarantine tank.

Interesting observations about the skirt tetras Matt. I guess as with all cichlids there will be some variance as to how they react, mine haven't been kept with small fish before, and I'm hoping that won't have increased their predatory instincts! I'll keep them well fed and see how it goes.
