Hi luke, what do you have her with?

i agree dosent look very happy ..i go with karrie her fins look a bit damaged and her scales to..

Male GT, Male kennyi, male Red Empress, Male peacock, 3 juvie frontosas.
Fins are a bit damaged, do you think it could be due to stress?
I plan to get rid of the male africans soon, they are sub dominants from my main african setup.

yes i think to many boys and they are harrasing her.. the male gt and male kenyi most prob your culprits.. male kenyi might be trying to mate ..others arent to nasty.. do you have alittle tank you can put her in and add some melafix to heal the scales and fins..
also you can give her abit extra food with out the others as well.. they might be bossing her out of her share..

get the americans out of the african tank , 2 different types of water and food required , put her and the male gt in a tank with some wood and feed them some meaty food and she'll liven up .

most GT'S if they get too much protein this can harm them. in the wild they are diggers and a majority of there diet consists of plant matter. also feed with spirulina flakes they are easier on the digestive system.

First and foremost, I would definately seperate them as Harvick said. In the past, I've had the best success with GTs in slightly acidid to neutral water - PH of 6.8 - 7.0. Your Africans will thrive around a PH of 8, so .. while it may seem like they can co-exist because they "get along", once there is damage to the fish that PH difference becomes even more signifigant, and can be the difference between speedy recovery and infection/disease/death. Plus, from what I understand, Africans and South Americans 'communicate' differently, so GT may not be reading the warning signs expressed by your Kenyi, Empress or Peacock, and may be getting pummelled because of it.
