But she is so aggresive...what is the male looks like?
Ian do you have pic for male C115?

Hi Jackson,

oh no, don´t call her aggressive, c 115 is just a bit crazy...
Your fish looks quite young.
Great pic, really!
The males look just a bit less round, and they are chasing their fat girls all day long if they feel good...

sorry, my male-pic is a bit poor, but it´s the only one I found:



and another girl:

I have found many of the long snouted species to be aggressive towards each other especially during spawning, There are definitely fights and squabbles to determine the top male and female within a group.

This is two female C. coriatae fighting, with their pectoral fins locked they were actively trying to get their fin spines into each others gills.

Hi, Ian, actually the bottom one in the photo is a young male C.coriatae. Look carefully at his pectoral fin you can see the yellow tough thing on the spine.


Thanks Gitta, your pics are really helpful, how big are they now?
My female C115 is about 6cm long. She always chasing her smaller tank mates such as C acutus and C116.

Actually Jackson they are both females. dominant females also show some odontode growth on their pectoral fin spines, but no where near as mush as sexually aroused males. You can actually see that both fish are swollen with eggs. The near fish proved to be the stronger of the two and produced more than 100 eggs in the first spawning.

Really?
I am confused now, how to sex those longnose one in a proper way?
There are two pictures, can you sex them for me?
I think they are both males.

Cannot see the pictures

huh? I can see them...two pics...

I am getting the pictures now. It is not at all easy, why I am certain about the sexes of my fish was because I observed the spawning activity. Can you view the fish from above and also see the shape of the ventral fins. Looking at the bodies of your fish they look female but that could be down to good feeding. I see the bushiness of the pec spines but a dominant male can show very prominent growth.

Ian

My cories are all very fat, the one coriatae above is the dominent in my tank.

That fowleri is only junvenile now.

Wouldn't the shape of the ventral fins (females' being rounded whilst males have pointed ventral fins) do the trick in determining the sex of the C. coriatae?

Hi,

really? She looks much smaller..
Mine is about that size an they are spawnig nearly every day.

I just had to laugh about your "she´s so aggressive"...
She is a longnose: She can´t do anything about it.


How many of them do you have? I have heard that C115 and C116 could be the same. At least it might be possible they interbreed.

Greetings Gitta

C116 is different from C115, its color is blueish, I will post a clear pic for C116.

Now I only have one C115, I found it in a tank of wild C julii, hopefully I would get some more in this winter.

The coriatae I posted there is a male for sure, he spawn with another female in the tank today.

It just goes to show how difficult some species are to sex, especially from pictures. being full of food or eggs can look the same.
