Help to sexing Sewellia Lineolata

Post by FreddieJ » Wed Jun 12, 2013 1:51 pm

Hey,
I have bought 4 Sewellia Lineolata, and read several guides how to decide what sex they are, but I find it hard to decide.
I'm hoping there is one who will spend 2minutes to help sexing them for me.

Last fish was not in mood for photographing, so i left it alone. I know quality isn't the best, but maybe it willl work out

EDIT: I can't see the image myself, so here is the link:

Looking forward to your answer,
Freddie

Pretty sure the first one is a male. Not sure about the others but they look to be males too. The second one looks to have a different body shape to it but it is not clear so I cannot be sure if it is a female. Do you see 'fences on all three? Males have 'fences' on their pectoral fins while the females do not.

Hi,
All your fish are males!

One of them looks like it's only the bones going across the yellow - no black markings, the rest seems to have a little black going across where the bones are, making "fences"

You can only see the "fences" from the front or top of the fish as they are actual raise fins on top of their pectoral fins. They are very easy to see once developed and are pretty much the easiest way to determine sex in mature fish.

Maybe my fish aren't fully developed yet, since I find it hard to see weather the black fences are there or not.

I.e. to me this male doesn't seem to show "fences". Have I got the fence thing wrong?

I agree, they all look like males to me.
