Yeah. I bought a few 2-3 inch Telmatochromis dhonti "orange scribble"... and they're exactly as I remember them. The most hellish little things with fins (IME only Neolamprologus Christyi can compare in terms of aggression), I swear, they just have an eternal hatred for all other fish. I picked them up from a local african cichlid supplier, and dumped the little things into a 90g with 12 exodons and 6 young hampalas as dithers. Within 10 minutes the dominant male had 3/4 of the lower half of the tank secured as his own, and had the others huddled into the last quarter of the tank. That's quite a bit of space for a 3 inch fish to claim - a 36"x18" floorprint and about 12" high - and he is just a solitary fish. I'm hoping for a pair, if he doesn't kill the others first. No breeding behavior whatsoever. The pair will be isolated in a standard 36g afterwards. He's quite the character though - he patrols his territory, examining every nook and cranny, arranging things to his liking. If there's a pebble he doens't like, he picks it up and places it elsewhere. He will continue this behavior with the single pebble until he's satisfied with where it is. Truly interesting fish for anyone who's willing to dedicate a species tank (or has 200g+ community for a breeding pair). Anyone else keeping these?

While this is not my fish or picture, here's one for reference anyways:

Do they have teeth? That pic makes it look like they do, and I don't know much about them. More pics please.
 
Yes they do have teeth... extremely large teeth. Bigger than any guapote IMO for their size. The dominant male paired off with a female, and has taken the entire 3/4 of the tank minus the top quarter now where the exodons school... the subdominant male and the remaining females/unsexed are attempting to pair off as well but the dominant male is stopping them. Might have to remove them soon.
 
Quick update - had to remove 2 female and 1 male dhonti and whichever hampalas were still alive - he allows one other female in hte tank, albeit not near the territory with his "main *****"... he has a special hatred for the hampala barbs as well. The exodons he doesn't seem to want to bother too much, he actually seems somewhat nervous around them if he's alone towards the top of the tank - where the exos congregate. He was keeping the hampalas and the other 3 dhonti at the surface - the entire footprint 47x18 is his now. At the surface though, the exodons seem to run the show. They were slamming on the 3 subdominant dhonti and even the more massive 5 inch hampalas (exodons ~1.5 inches) - the exodons had already dismembered 2 of the hampalas before I got home from work, so I removed the others before they suffered the same fate.

Interesting to note, the Exodons seemed to sense the hampala's stress and as a result predated on them. They were together in a 55g for about 5 months with no casualties, just the odd squabble. However, now when the hampalas are herded towards the surface and being attacked by the male dhonti, the exodons are getting far more aggressive than they were before.
 
Yeah to me that guy in the first post just looks meaner than hell lol. I hope things have calmed down a bit and no further fatalities.
