hey, i have a trimac, hes pretty spunky, and in reply to the has to be a male with the hump, i have a female that is about 4 years old with a larger hump then any fish i have ever seen in person. shes an f1 from wild captured fish tho. you should look at their sexual organs about once a month, females have a large white stem and males have a small little weenier. male midas will clean out a spot and usually not care about how large his mate is. either way, hump means NOTHING!
