i got one that was supposed to be male but i think its a female.. the fins arent pointy and it had no color.. i gave it to my brother in law for his mixed tank.. i have way to many fish so i stopped trying to get more fish.. i have thin out my male mixed tank.. and this fish wasnt really mellow
mine has a little yellow on the tips of it's fins. i will have to look & see if the fins are pointy.
i have a sulphurhead that was sold to me as a male & he acted like a male (chasing & bulling). recently i caught him (her) with an egg chute down, doing the dirty dance with my blue dolphin. i have an all-male tank & things are pretty mellow with the female in there (so far).
