One of the reason I keep them is that S. pindu are such unique creatures.
I've males grow to 7-8" but they'll breed at 4" or so.
I think I've given away, donated or traded dozens and dozens in the past few years (they have relatively small spawns, in my experience).
The ONLY wild locale for these guys is a single crater lake (Barombi-Mbo) in Cameroon, so their existence (along with all of the other Barombi-Mbo endemics) is precarious.
I hope that there are folks in Europe breeding them. If not, I'm happy to donate some if you can find someone to handle the shipping and permits.
