This is the best pic I could get from 20 mins of sitting by the tank snapping pictures lol, sorry its a bit blurry it was taken from my phone, my camera is not working at the moment. He/She? is a little over 2 inches. Picked up today from my LFS, the owner called it a Red Pearl Flowerhorn. (The tetras you see are in the background picture not in the tank with the FH)
Prolly a female...even at that size, most males will have a small hump. I bought my FH when he was an inch, and his head was already starting to pop a bit.
