Thanks Again Guys.
I was going to put them in a 20 long divided, but they hated itwhen i tried it.
So i will leave them in the Acrylic Cubes untill i find something more suitable for them. as advised by the breeder.
i might try them in 2gallon lentil jars this week and see how they get on.
They breed the same as normal bettas and i am looking out for a female that won't be killed by the Purple guy.
