Hi guys,

i have just noticed one of endlis fully cupping his anal fin! wow! 1st time i have seen it... the funny thing is, he is only 9"...i havent even seen this behaviour from my 13" males...i was like woah! sikkkk! :headbang2

Is this normal at this size?

i'll try and get some pics...could take a while tho...

cheers,
e.:D
 
:iagree:
not really a size-related thing...as long as the anal fin has developed enough, of course.
 
Hehe...yeh...i just got home from work and ive been watching him for about half an hour...he's still goin...like every 3 mins or so...and especially when one of the other polys comes near him...

i was thinking maybe its like a puberty thing? like an adolescent boy who cant control his...you know...:naughty:

what i cant believe is that i have not witnessed any of my larger more mature endlis doing it? Or maybe the larger ones that i thought were males are all females...? lol.

got some decent footage and pics...i'll upload it later...

cheers,
e.:D
 
I got an endli that's only bout 13" does the same thing.......
 
My 16" congicus male does it all the time, even though he's been isolated ever since I got him! So it seems to be an almost involuntary motion where he "cups" his anal fin and "flares" his caudal fin. My question for everybody out there is this; does your male "cup" to both sides or just one? Is he a "left handed cupper" or a "right handed cupper"?
 
just stretching? really...so nothing sexual about it? surely its more than a mere stretch...on account of his added "wierd" behaviour...ie:

- swimming to the surface then slowly sinking while cupping the anal fin and displaying his back fins...( similar to what is written in the stickies... )

- constantly seeking attn from the others in the tank...

Oh, btw...its interesting to note that he has only ben doing this since i turnd the heat back on...it is now moving into the colder weather down here and i decided to bump the temp up... it was sitting at around 20degC, now at around 28degC...could this have anything to do with it?

cheers,
e.:D
