I love Nannochromis teugelsi but will they thrive in your black water tank? I thought they need high double digit GH.

Not to be snotty but if you love them you would know they are a blackwater fish:

New Nanochromis found in Congo - Practical Fishkeeping

www.practicalfishkeeping.co.uk

(from above article:
Habitat and reproduction"The particular locality where the holotype was collected was a protected backwater connected to the main channel, with a sandy substrate and some aquatic vegetation, including submerged grasses and floating Eichornia."
)
(bold is mine).

The lake african fishes are hard-water fishes the fishes from congo river (or west africa) are soft water fishes; though most will easily adapt to conditions a bit harder than blackwater.

My guess is you were thinking of the shell fishes which include:

Neolamprologus multifasciatus
Neolamprologus similis
Lamprologus ocellatus
and several other species from the genus lamprologus and neolamprologus neither of which is the genus nannochromis though i admit both neolamprologus and nannochromis start with an 'n' and both come from africa.

Neolamprologus multifasciatus
Neolamprologus similis
Lamprologus ocellatus
They would die in double digit GH. They require GH greater than 250 ppm. You are snotty.

Well you said double digit gh - so for example 15 gh is 267 ppm.

You are correct. I meant ppm. But I did think, perhaps wrongly, that Congo based river cichlids swam in waters between 50-100 ppm. I thought black water was less than that.

Anyway he is sold out of male teugelsi so i went with nanochromis transvestitus (which are not as colourful but a bit smaller and more reclusive and more demanding on the blackwater side needing ph below 6 to breed).
