So I bought a Red Devil from my LFS thinking it was a female because it was about 12'' and had NO BUMP what so ever... not even alittle bit... so I go out and buy a male flowerhorn last week thats 9'' hoping they would mate and they got in a fight the first 30 seconds they met and the red devil beat the hell out of the flowerhorn... so I come home today to find out the red devil is a male, he all of a sudden out of no where has a HUGE HUMP on his head... pretty funny... wanted my RD to mate with my FH, oh well.. funny stuff
