Well, now that I've actually seen a red ackie. It's obvious how one can tell. The red ackie is all RED and the yellow ackie has a more dule red-yellow look to it. It you look at some pics of both it'll become clear.
It's funny that I'm learning this almost a couple years later after receiving ackies from Husker Exotics. Man, I trust people too much. I take partial blame for my issue. I should of done my homework on ackies.
What's worse I even let that business get off sending me a sick female. He told me she just laid eggs so she's thin, well she never gained any weight and finally died. It was pathetic. I thought I did something wrong when she died so I never complained. I now realize a sick misrepresented yellow ackie was sent to me. I got this "pair" in a trade for an adult female Cuban rock iguana. I regretted that trade from the day I did it because we really missed my ig. Now to find out I this unfortunate information really bums me out. No, it pisses me off!
