Hello! So I got this guy about a week ago on a local petshop. It was pale and it almost does not have any visible kok. I started taking care of it for awhile. Colors were a lot better and kok is pretty much visible. Then earlier this morning I saw a tube growing (or atleast what my eyes are telling me). Which in my knowledge, indicates that it is a FEMALE. So my questions are, is it a male or a female? Because as far as I've read, only males would have grown kok that fast considering the time that I've got him. And lastly, is it considered a female if the tube is visible? Oh and BTW it is only 1.5 inches. Which I think is pretty young for the tube to show up. I'm new in flowerhorn hobby. I've done my research before purchasing one. But this is beyond my knowledge. So I hope you guys can help me on this matter. Thank you so much in advance!
