Cloud minnow or Pencil fish?

Yes, the markings are what caught my attention too, but I just figured maybe the females are marked differently. My apologies to Quantum! I looked online and it DOES look like a Cherry barb to me. And I remember when I got this fish that the tank was labeled White Cloud Mountain Minnows, but some of them were bright red! I couldn't figure out why. So it makes sense--they were put into the wrong tank! Good ole' Petsmart. I don't buy from them anymore. Just read about the Cherry barb, and thank goodness they aren't nippy like most other barbs. So I really lucked out! I won't have to take her back, and I will go out this week and get her a male. Poor thing, she's been sort of hanging out with the minnows, but mostly by herself. She's so mellow and kick back, and I thought all barbs were hyper and nasty! So I'm actually a little pleased. Thank you for the help, both of you!

At least 75% of the fish I've gotten at Petsmart have been sick and died, and it was from one of their fish that I got a virulent form of Columnaris in my tank. I think it's finally gone now--been a long 8-9 months! And I lost MANY fish to it. I do research fish before I go to buy one to be sure I have the right PH, temperature, tankmates, etc., but since this fish was in a tank labeled White Cloud Minnows, and I knew the females were bigger and fatter, I just assumed that's what it was. Didn't look closely enough. I'm going to an LFS an hour away next week to get her a male. I haven't gotten a sick fish from them yet. I saw her chase one of the male minnows today. I'll watch and make sure she's not making a habit of it before getting a male. That could be double trouble! Maybe its just because she DOESN'T have one of her kind. I hope so. Thanks again.
