Pelvicachromis Pulcher Ndonga

Greetings,

I had a very small aquarium back in the days, now that i've grew up a little
i want to try reproduction of P.Pulcher Ndonga.
I am planning on buying a 300L aquarium soon, though before i start anything
i want more details on my future subject

So my question is, would anyone have a URL to a great guide to keeping
P.Pulcher in good health, which species can i use along with them... well in
fact consider im a noob in aquaria, so lets find a guide with everything
from what is needed for the aquarium itself to the maintenance of the
P.Pulcher...

Is anyone able to help me? or direct me towards a guide?

Thanks a million times!
