Valid points in adding wood/rocks.. Did you notice any difference in aggression before and after adding wood?
Another reason I didn't plan to add wood is due to the space they take up in the tank.. Nonetheless, I will heed the advice that you and the others have given and look for some wood, if I can find any that catches my eye..
I looked through the
link and noticed that most of the female GTs are aggressive towards their counterparts.. Do the females only chase/attack the males?
Does more GTs in a tank reduce aggression or is it the same either way ie the weaker ones will get bullied by the rest?
Onto my GTs update, they are doing ok aside from feeding time.. GT1 went from anti-pellet to pellet-hogging and would just chase GT2 whenever GT2 tries to go for the pellets *facepalm*
So I had to improvise and put the pellets in little by little so GT2 gets to eat as well..
