Sex this Thai Silk Flowerhorn

[PufferFreak88]

Is this a Male or Female Thai Silk Flowerhorn? the fish is about 3"

I think my Thai Silk Flowerhorn is a Male because I can see the hump on its head starting to develop and the body form as well and again I'm 80% guessing that its a male but I need a second set of eyes to help determine the sex of my Flowerhorn.

BTW does a male Flowerhorn have a tendency to dig up gravel in the tank? or is this an indication of the female Flowerhorn behavior?

looks like a female to me. the dorsal fin is a bit round. flip it upside down. if the anal vent is U its a female. and if it looks like a V its a male.

looks like a male 2 me

Yeah I would think its a male.

If the vent tube is skinny and darker, most likely it is a male!!!! You can not judge a fish by its fins. Just my 2 cents!!

Looks Female to me......everyone has a different opinion I guess you will have to wait and see. I say female because at 3' i really do not see any sharp angle or slope in the forehead (kok).

I vented today and indeed the tube is very dark.

Dont the male usually have a muscular cheek? broader body? My flowerhorn seems to have these features at 3" but the anal fin is not pointed at all.

Can you get a closer pic of the vent? My guess is male.
