Stocking question

[cometcattle]

I have a pair of Fundulopanchax gardneri in a 5.5g(US) that is heavily filtered and heated to 79F. They share the tank with 2 ADF.

Would I be able to put another pair (F. gardneri) that is currently in a 10g community in the 5.5g, or would I run into aggression problems?

Thank you.

I maintain a bunch of sub-adult GAR N'sukka together with Ps annulatus. These were raised together since young, so the larger GARs don't harrass the clowns.

Introducing another male or pair may spark off a pecking order, so just be observant.

More importantly, GARs can hybridize readily and it's frowned upon, to have 2 different species (or populations) in the same tank.

Thanks for the info.
