HAPPY BIRTHDAY!My purple was in the tank for over a year before him, and fortunately my purple has always been a very laid back tang...so he cared less when the Achilles was added. The Achilles on the other hand is a serial murderer...LOL. Only issue you may have is the powder brown/blue and the Achilles are all from the same family (and same shape) so you have more likelihood for aggression problems.
What?HAPPY BIRTHDAY!
