I have six of these titchy little guys, but don't worry, the tank is huge. D'you guys think they would be compatible with a betta? None of them nibble each other, and they seem pretty mellow, if their none-reaction to my cat is any indication. (I appear to only have one male judging by the colour, so hopefully there won't be much aggression between the barbs themselves)
So, any ideas for compatible species? I know tetras are slightly out because of their fondness for the nibbling (at least, according to the guy who sold them. Might just have been the Phantom Tetras though), but there isn't much else on offer. I was thinking about a Guppy of some sort, or a Green Swordtail - but I'm not sure if those two are Betta friendly.
Also, what species of catfish would you put in? Is having a catfish at all a good idea, even if I call it Rupert?
Also also, suggestions for names? I named all six Barbs Theseus, my two goldfish in a separate tank Lancelot and Merlin (yeah

), and am currently scouring the 'net for a list of Thai names that won't make me sound like an idiot when trying to pronounce them.
Finally, I'm a newbie, so hi!
