What size is your tank? What other fish do you keep with them? What substrate? Any fertilizers? Temperature? I assume you use conditioner with water changes?

Geos are generally peaceful fish. I used to keep a colony with 2 breeding pairs and never had any issues.
Havent kept fish in a while but I recall them requiring vegetable matter in their diets. Pellets should be small at their size, sinking 0.5mm so they can sift through the sand. Probably feed them less brine/bloodworms.
Also, I'm pretty sure they can be a bit sensitive to unstable water parameters (i.e. constant water changes). Maybe do 10% every 2 days and 15% every 3rd change which is still 45% water change every 6 days but a bit easier on the fish.
Or could just be the other fish. Also, fish can get quite aggressive at night considering that when a fish is found dead, it's usually in the morning.

Different male peacocks should go fine together amongst the yellows.
If you want a bit of blue in the tank, have you considered blue dolphins? Quite nice fish and should get along with the others.
Otherwise everything seems okay

Maybe remove the cobalt blues as they're herbivorous and the others arent, otherwise all should get along fine but I wouldnt mix the dragon bloods and red shoulders because they will cross breed unless you keep only males.

As with most africans, usually you keep 1 male : 2-3 females for breeding.

For display purposes you can go all males but with previous experience I've found males colour up the best when their's a female to show off to as well as another male to 'challenge'. Just note the subdominant male(s) wont look as nice.

Maybe stock 1-2 males of each peacock and
2 males and 4-5 females of the rest of the fish.

Jack Dempseys with electric blue gene PAIR

Male is about 22cm and female around 17cm.
These guys appear as regular jack dempseys but actually carry the electric blue gene.
25% of fry will be electric blue jd's, 25% will be standard jd's and 50% will be carriers of the electric gene.

I paid $300 for the pair from Living Pictures (one of our sponsors).

They have bred twice in my tank already without ideal conditions but none of the fry made it as other fish had eaten them.

$150 to get rid of them 

 

Thank you

 

Sold

Last few fish, JD's have bred once again, slowly gaining experience.

Female polleni was murdered so male is for sale individually.

My Jack Dempsey's have spawned. Might try raising the fry until the pair sells. Anyone have any tips?

Even more updates, jd's have officially bred.

Added some tropicals as well.

Someone is selling 8 brevis for $60 on gumtree.

Bump, updated list and discounted prices
