Hello, Id like a second opinion on sexing my L260. I think the one in the middle is a Female and the other two are males. its weird though because the female is always in a open back cave and attacked anyone that comes in. They might be a little young to accurately sex their about 2.75". Thanks!

Hi,

it all depends a little on how long they are in captivity and how well they have been fed recently.
The middle one seems to be a male.

The other two are difficult, because they are not lying flat on the bottom and hence head shape is not clearly discernible.
I´ll give you 60% male for the other two, a more reliable guess is only possible with better pictures.

Cheers,
Sandor

Thanks Ill get some pics of them individually tomorrow.

Based on the first photo, fish on the right is surely a male one. Middle looks like a young female. Unsure about the fish on the left but could potentially be male also.
Females can be aggressive and territorial as well, nothing to be worried about.
