The catfish are M. paynei.

the secret is... I don't friggin' know. So here's the story about these guys. I ordered 4 (all I could afford) from a Batfish pre-order not long after I got the tank. Since the tank was empty and everything was from the same source I planned to throw everything in and skip the QT step. I had some pelvicachromis, congo tetras, and the catfish on order (this would've been at the last catfish convention) all to help distribute aggression.
Unfortunately, only the murder noodles and pelvicachromis arrived from the distributor. Batfish was awesome and still got me the rest, but they came later.
Also unfortunate is that this was my first experience using a sump and, as the set-up was 2nd hand, some dunce had carved out some notches at the top of the overflow. I lost 2 murder noodles and 1 pelvicachromis over the sump before I figured out what the issue was. I had to move the remaining pelivicachromis because, as the only dithers, they were not faring well.
I was left with 2 murder noodles. The larger of the 2 stressed the other to death (or at least disappearance). Over time, my big mean noodle was a) obviously male and b) terrifically boring. I wanted more, but finding them was difficult. The congo tetras and catfish livened the tank some, but it was just SO boring. I decided to try the Stomatepia pindu, since they seem pretty tough and don't occupy the same space as their murderous tank mates. They've made very good dithers (better than congos who really stay high up).
Of course, shortly after I added these, Jeff Michels came to town and he HAD T. brichardi on his list, but in pairs. So I pm'd him. I needed extra females. I settled on 1 male and 3 females and quarantined them in a 20 long filled with bamboo pipes (like, seriously, FILLED) with an extra powerhead for water movement. I ended quarantine when the females killed the male. A few months later, my original male seems to have picked a female and settled down to start a family. Of course, he's got 2 spares should he get irritable and kill her.
The moral of this story is that plastic canvas makes a great patch for messed up overflows...
