Apparently, i hope you have got her "measurement" drawn because i feel that by knowing the proportion of its feature will help to determine the sex of the fish.
The length of her pectoral would suggest that its a female. But of cos, the size of the pelvic fin as well. However, this "theory" of mine does not seems to be applicable to L24 or L25.
Don't worry, from the pics that you have posted when you just got those fish. I could see 2 females from Group A and 1 from Group B. So the chances of having females in your colony is still high.husky_jim wrote:

From what we have discussed in hannover and by examing all my pseudas i think that your theory of determining the sex based on fins has a great % of accuracy!
...i believe fighting as well...we will seealga wrote:Teribly sorry for your loss.
One thing I noticed was the darkening from the left pectoral down toward the mid-line of the stomach.... fighting or heater burn maybe???
i second your conclusion!good luck with yours too....i think this spieces is the 'easiest' among pseudacanthicus to try to breed....Haavard Stoere wrote:Sorry for your loss. Great documentation
I took out all of my 6 L65s this evening and concluded that I have 3 males and 3 females. The females measured 12cm tl and the males measured 14cm tl. At least one of the females was gravid. Sexing this species is dead easy because of the extremely different head/body shape and size of both dorsal and pectoral fins.
I hope you dun mind if i added some pics of mine when i did a autopsy on my spinosus. It also suffered from sudden death.. and the most heart-breaking is to see those sacs of eggs.husky_jim wrote:

I will take new pics when i will be sure that nothing is wrong with the fish and/or tank.Probably next Saturday....Haavard Stoere wrote:Are you sure you have any definite males? To me all of them look like females. If there are males they didn`t look very masculin when you photographed them. This might have changed since you bought them.
Why not make a new photosession and photograph them one by one from above and in your hand from the side to compare dorsal fin size.
