Glad you figured it out. *I could've had a V8
Never had them but they do resemble cherry barbs. I understand they get a bit larger, though (3" vs 2" max).
Yes, I have several. I really like them: they are very active but don't bother their other tank mates, even the long finned ones! They are aggressive eaters, but so are the other fish in the tank, so no one out-competes the others.
Edit to add: they also look really nice against black sand!
Odessa barbs are so pretty: good choice! I was actually looking at the Odessas at my LFS the other day, and thinking I need to get some, someday. (But not now: I already have too many fish!)
