Oh, I thought certain fish do better if they've been together since they were young! Guess not!
I'll try to give the knife and other fish a head start before adding the ctenopoma, that seems to have worked out for you.
The Hoplo seems cool, but I'll let Byron chime in on that. I do want a catfish for sure, and a hoplo appeals to me. Otherwise I'll probably go with a school of upside down cats.
I love kribensis, so I may try a pair of them for the tank. (A pair won't damage any of these fish I'm pretty sure).
As for the school.. I found these guys and it'd be great if I could get a good size group (they are big enough to live with the knife, right?) Something duller for this crazy group of fish:
Arnoldichthys spilopterus (African Red-eyed Tetra) — Seriously Fish
Or these guys, a catfish that mid swims:
Pareutropius buffei (Three Striped African Glass Catfish) — Seriously Fish
As you can imagine both of those are probably rare so the fall back plan is congos.
Thanks so much! I'm glad this is coming together finally!
African knife x1
Hoplo catfish x1 OR upside down catfish x5-6
African butterfly x1
One of the above schooling fish x8(? or more if I have room)
(If there's any African tetra I'm missing I'd like to see them too)
