I seriously lucked out today :] Went to the Local Shop and they had a ton of amazing and rare fish! Unfortunately, they didn't have any barbs I was interested in, but I did get a bumblebee catfish for my 20g! He was only 4$ as well, it was a pretty awesome place and good timing, as they said they rarely have bumblebees.
Then I went to the chain store because I needed some reptile supplies for cheap and they had new arrivals.. Odessa Barbs! They were very washed out color-wise, but hopefully I'll be getting them back to their natural color. I bought 5 of them today, and if all goes well I'll be going back in a few days to buy 5 more. They already make such a pretty school in my tank. My angelfish has been avoiding them, but I haven't had any problems yet.
Now I just have to hope my catfish doesn't decide they're lunch. They've been hanging around his territory, but he doesn't seem too keen on attacking them, just a little annoyed. They're about 1.5" now, and quite round, so I don't think any of my cats will try them for lunch. ;>
I'll upload some pics of mine soon, but here's a shot of one I found on google, hopefully mine will get this pretty.
Yay.. now my 55 is complete :]
