Well to be hounoust I haven't looked into that, because it is a non-endemic cichlid of the Malawi lake. And I can't remember seeing these on a stocklist either.
I guess I could order these fish at the importer if I want to, but I'm not really into non-endemic species.
Its a fish that isn't normally kept as far as I know. Why do you want these? Because of their size?
The Rhampochromis family grows up to 20-25 inches as well.
When I have my large tank finished once I have my breeding shed, I want to import some Novochromis Livingstonii as well.
These fish get that large however that they aren't caught for export normally as they can't be kept in a normal (what is normal) aqaurium
