definitely some questions with this batch. i bought mine (4 of them) at a different source but they were also labeled as "red tiger sev" so i'm thinking they may have been from the same breeder. all of mine have the proper half bar, and when i was looking at them in the tank i didnt notice any with a screwy bar. i also didnt have the issues with ich like some of you had, but mine refused to eat in the beginning. i went through metro once and got 2 of them eating well and quickly out paced the smaller two. i probably waited longer than i should have before treating them again, i thought they were just being out competed for food but the smaller 2 are only just starting to put on size now. i'm a little worried they will be stunted but hopefully i will at least be able to get a pair and some fry and then i can get the pick of the litter.
