Hello my name is david i have a 100 ltr tank. the occupants are 2 one and a half inch green terrors brought together at the local fish shop. they seem to get along fine at the present time although the dominate brighter one gets a little agro during feeding.

How long will this peace last

what size tank would be appropriate when there relationship fails

any other advise would be greatly appriciated

i am simply captivated by there colours and intellegence please help me to care for them thank you greatly

wow you posted this in alotta places.
So the same reply.

Having personally kept and bred these fish i kept my breed pair in a 3ft tank on there own. giving my male was 10.5 inches "check avatar". if you've got both males i can see aggression developing later on in life, two females are usually more calming. Male and female pair woud be great.

I agree with you on there intellegence and beauty,
Terrors are too often dismissed because f there common name.
