These are all Koonacs that we have in our aquarium, we are not sure what brand they are. They are quite aggressive and punch each other in the nose a lot. Sorry about the terrible photos, I'll get some better ones and figure out what species is what soon.
These Koonacs share a small tank with several one spot gambusia , a small marron ( cherax cainii) , a few gilgie (Cherax quinquecarinatus or C.crassimanus) and a very small Yabbie ( cherax destructor or c.albidus).
