Indos...have to be in odd numbers??

[Col-Dats]

I have 4 Indo's, 4 Thin Bars and a NGT. All get on fine. Used to get alot of fighting amongst the 4 inch dats until I added a 7 inch Indo and that sorted all the problems, even with the NGT. The new Indo was the largest dat and the boss so now no problems, just the odd rumble at feeding time. As long as they all have their own space to sit and direct eye contact is restricted then all seems to be fine.

i have a small 1.5" indo with silver dollars angelfish and all sorts of catfish, hes doing fine alone cruising the tank and eats like a pig. he outcompetes the angels for food. in my other tank i have 5 tigers., 3thinbars all about 3-4inch a six inch at and a 3 inch at. they all used to hide, just get out to snatch some food and go hiding again until i got the 6incher. they seem more confident now and are out and about more often. they do bicker a little but no damage is ever done
