im not really into cichlids but this variety does peek my interest. are they like all other cichlids? only to be kept with cichlids?
 
From what I know it depends on the species but for the most part easy going also keeping them in groups is yhe way to go. Also heard that red head tapajos are mild can be kept in singles, and some species need cool down periods. Wait for more experienced members to chime in though

Aggression is usually relative, depending on factors like what else is in the tank, tank space, adequate or inadequate numbers of a particular species, etc. Geos vary, depending on family, or even species within a family. Some are feisteir than others.

I wouldn't say cichlids can only be kept with cichlids, many or most can be kept with a variety of other fish, whether catfish of various kinds, cyprinids, tetras of various types, etc. All a matter of compatible species, whether mixing cichlids with cichlids or mixing cichlids with other types of fish.

It's a pretty general question. With more information... tank size, what else you have in the tank, what kind of water, etc... you could get more specifics on whether geos would work in your tank-- or which geos would work.
 
As stated above, with more info on the tank size, stock intentions, species of Geo you're interested in, etc, then we will be able to give a more detailed answer.

However, as a general thought, they aren't an aggressive genus of cichlid. What little aggression some species of Geo do show seems to be completely conspecific. I don't recall ever hearing from anyone about their Geo going psycho on their other cichlids or catfish, but many people have reported high conspecifics with certain species of Geos. If kept in too small a group or if feeling cramped, they can be pretty rough on their own species and sometimes other species of Geo. This is where knowing your stocking intentions/ideas will allow us to support or critic your ideas into something headache free. :)

As some have stated on here most of them are not aggressive towards other Cichlids but only to each other geo. I have owned the alfatrons, Jupari, balzanii, red heads and also red hump. The alfatrons that I have in groups of 4 will lip lock and nip at each other from time to time. I will say the red hump that I have is aggressive towards my peacock bass and bandit Cichlids. And he's smaller than my peacock bass. Geos are fun to watch if your running sand in your tank. Good luck

Usually I skip over the cichlid sections at my LFS, but these caught my eye. One store had them in a community tank with tons of other fish (small tetras or something) which made me start thinking. I'm just trying to get a general idea if it's even something to think about. Now it seems like it might so here's some specifics. 29 gal- 3 angels, 1 leopard leaf, 1 roseline shark. Tank has sand.... or 55 gal- 1 syn. Cat, 4 clown loach, 1 eel, 1 small pleco. Tank has gravel.

Geos do best in groups of 4+ when they are young. Once they reach half their max size (varies from species to species, but the smallest geo species hits 5-6") they can be kept singly or in pairs. A 55 would be fine for a pair of sub-adults of one of the smaller species of Geos, but you might need to start with a group and whittle it down to two as they mature. If they are small and you don't start them as a group, they can become recluses that just hide all the time even when adults.

You would also need to change the 55 over to sand. The eel would appreciate it and the geos would need it.

Those clown loaches and the eel are going to get massive too. Do you have plans to upgrade?

I have a 135 gallon and planing on going even bigger in the future.
 
I have owned a large number of geophagus and satanoperca and currently mix 5 different species as single specimens and have no aggrression what so ever BUT it takes a while to get the balance right. If you are not going to do a group (4+) I would do single species mixed together as 2's and 3's of the same species will chase each other. Personally I wouldnt do male red humps or braziliensis (not technically a geo) as IME after numerous attempts I have never successfully mixed them in other geo's.

With regards to geos being aggressive with other fish such as tetras, I have never seen this and currently house mine with a shoal of lemon tetras, a shoal of rasboras and some corries and they get on just fine.
