When i upgrade my geo tank to a 105g 6' tank. I would like to add either a ebjd or a pair of threadfins. What would you choose? Or would the threadfins not work?
Stocking is:
a pair of dimerus or 1
5 red head tapajos
1 dicrozoster
1 altifrons
1 Chocolate cichlid
1 heros notatus
1 bristlenose
 
Clear choice is Heckeli!
 
I wouldn't comfortably introduce a "pair" of A. heckelii into that setup. They're quite con-specifically aggressive, and in a tank that size with only two of them I'd be surprised if you didn't have problems with them.

I think you're borderline overstocked as it is.
 
I also forgot about the red Bahia. The dimerus are a question. They might be solo in a tank for breeding. More than likely that's where they will end up. So it would be all the fish in my signature. Could I do just one. I won't worry about nitrates because it's filtered by a sump with 600 gph and a 402 with a micron filter and and twice a week 40% water changes.
The pair was going to be male and female.
Thanks for all the advice guys(in advance)

one more question
are the threadfins geos or acaras because I have seen them as both?

They do best in groups of at least 4, but I'd be more inclined to say 6 for A. heckelii. Male and female doesn't necessarily mean it will eventuate in a pair, and there are a multitude if issues that can occur with this setup.

- Male and Female consider themselves incompatible, constant aggression.
- They're not sexually mature (18months-2years for A. heckelii I believe), male reaches maturity before female, constant aggression as a result.
- Being cave spawners they like plenty of room and a very large pot. They'll want 4' of that tank, and with it obviously being quite thin for that volume in a 6', that means there's no room to go around them. Hope that doesn't happen in the middle of the tank.
- There isn't enough room for them to spawn, more than likely resulting in conspecific aggression.

Like many shoaling or social species, boys like beating up girls. With only two in there, unless they're an absolutely guaranteed compatible and developed pair, the male will just constantly harass the female. I ended up selling my beautiful shoal of 4 because a developing pair took over an entire 4x2 footprint and had the remaining male and female cowering in the dark upper corners of the tank. They are ruthless, and after being perfectly fine and sociable for months the 'pair' suddenly snapped.

I don't see the point in doing just one personally, if you want more fish and believe your filtration and maintenance routine can handle it, start expanding on your current shoals. Perhaps sell either your G. dicrozoster or G. altifrons and expand the shoal of the one you decide to keep. I'd leave it at just the colony of Geophagus sp. "Tapajos Orange Head" with a couple of Heros sp. though, personally.

They're an Eartheater. Only members of the Genus Geophagus can really be called "Geos". Acarichthys is commonly described as a bridge genus between what we commonly know as Acaras, and Eartheaters. They're fairly predatory towards smaller fish, and are generally more aggressive.
 
Thanks japes, I have done some research on them but I never know until I get some one with true experience. Yes I am going to rethink this and maybe expand my schools or something. I know I am going to add a school of rainbows.
 
Ya no I love my geos, 3 are wild caught and 2 are from rapps. Actually the rest are from rapps except the Bahia(Ken) and the chocolate. I got my wild caughts from snook. You can get them from him but they cost a lot ($120 shipped).

Yeah I know, what's not to love about them. I've got 3 Rapps red heads now. Looking for a few more though. I would probably sell the other eartheaters and get a few more red heads myself. Increase the size of your already nice shoal.
