Ok I got some mixed advice and just decided to go with my own. I got a pair of kribs today, they are about 2 inches. I set them up as the only two fish in a 10 Gallon tank. I planted it (artificially) and added a pretty cool artificial cave. I'll get a picture up tomorrow. I read up before I went to the LFS and me and the owner scoped the tank and I'm pretty sure I have a male and female. The female has a nice round pink belly and and a more rounded dorsal fin. The male is less colorful and has a more tapered pointed fin. Within a few hours of getting them set up in their new tank their colors really came out. The male wasn't colored real brightly before but now his dorsal fin is edged in red/yellow and he's even got a little red on his belly. The female is still pink bellied but the rest of her has colored up a pretty vivid yellow and her dorsal fin is bright yellow on top. Anyhow, they are the only think I have in the tank, it's filtered with a cycled sponge filter (a hydro IV I believe). When I first put them in the tank the female seemed to chase the male around a bit. I left them be and went out with the family and came back and now they appear to be getting on famously. They are sticking pretty close and eating together when I dropped some bloodworms in. In fact they had a little Lady and the Tramp spaghettI scene with the bloodworms, a little more aggressive slurping though. Anyhow, we'll see how it goes. So far, I'm really liking these fish.
