About parauchenoglanis, at least two species grow larger, p. punctatus and p. ngamensis that get to around 18"TL. This year I got some p. guttatus and p. monkei from Wetspot, also a couple of notoglanidium mactostoma. All seem to be very slow growing and will probably not get very large (maybe 8-9"TL?) as their growth rate isn't like the larger species I mentioned. There are others in the genus of course but I've never seen any of them for sale except a former p. balayi I had, even p. punctatus and p. ngamensis are extremely rare to find (haven't seen any in years). These fishes seem to just show up as incidental oddballs and are commonly mis-identified anyway. The rare one's I've found over time have come from a direct African fish importer (bought the whole batch, a mix of p .balayi & p . punctatus) and a couple have just shown up at my LFS! I would like to find another source for these fish too, obviously.. As Viktor mentioned there are a few auchenoglanis species that are rumored to stay smaller but also rare in the hobby. I should mention auchenoglanis cf. "bouche" isn't one of them, a pair I sold grow to 24"+ with their second owner. Most parauchenoglanis that show up are usually from the Congo River. After re-reading a revision of the genus it seems that p. guttatus and p. monkei may be the same species? My juvenile's of both look very similar with slight differences, too soon to tell really, time and growth will tell, rarely see 'em anyway as they all hide in the driftwood..
how large are they currently? any pics?
I don't have the best-looking pics where all of them swim in formation at 45 degrees to the bottom. That looks awesome.
Until then, this may do:
I actually find this tank extremely appealing. I may just have to get a couple limas and see how they do. how are they growing for you, fast or slow?
