For $64 why not buy one and grow it out?
Back in the day that was pretty much the only choice you had..... Which coincidently is where a lot of us got most of our experience......
Perfect example - guy sets up a delicate balance of Characins and introduces a fish he just stole from the LFS - surely they accidently sell mislabeled fish for pennies on the dollar - Wanna guess how the story ends? Might have something to do with that black dot. OR might just be a figment of someones overactive imagination......
For the record I DO enjoy being proven wrong - I'll gladly admit being wrong, when I am wrong.
