    Hi, my cory’s but actually in my friends tank.
    I gave my freinds 2 a while back and they’ve done very well, over 2″ now head to tail. Tonight I visited and they said, look, eggs on the glass and leaves. Had a good watch and noticed it was these, trouble is they’re BOTH depositing eggs. Something has spurned them to both do that at the same time.
    I’ve had a quick read via searchs on google and looked here but a little confused.

    Some info states “female will deposit eggs then look for the male and nudge him to get sperm into the mouth then go fertilise the eggs”
    On our knowlege database it say’s they interlock pelvics to fertilise the eggs in a T shape, surely this would be a + shape?
    Two different scenarios.
    The ones in their tank look the same, fin shape and from above and I’m thinking of giving them my other 2 to add the group of albino’s and adolphi’s. One of mine looks the same shape etc but the other may have a slight pointier dorsal fin.
    Anyone here got experience or know of breeding these, any other sexual things to ID m/f? They have the tanks running to use as a breeding tank if need be.
    I could keep trawling the net but rather ask here /smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” />

    Richy were you reading the Cory aeneus profile? It’s one of the really old unedited ones. Most of the other cory profiles have been sorted to some extent so please try one of those instead. Sorry about that.

    Best way to sex them is to look from above mate. It should be really obvious if they’re adult fish. The males should be noticeably slimmer and are usually smaller in size and have thicker pectoral spines than the females. I wouldn’t use fin shape as a means of sexing in these domesticated fish. Also I’ve had female corys lay eggs without males being present before. Cold water changes and imo changes in atmospheric pressure can stimulate them to do it.

    hi Richy , Matts right on the breeding precedure i’ve got a pic of habrosus in a lock if i can find the pic i’ll put it up to show you what is meant for the T position.
    it is known that females will get rid of their roe without a male being present bud.

    cheers Matt, yes it was the Cory aeneus profile /smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” />
    These are ina 5ft tank and it’s being upgraded to a 8ft and alot of stuff has been moved out so wasn’t sure it was the disturbance of it all that triggered them off. Weather, well we’ve haad alot of atmospheric changes lately so it may have been that. Water changes haven’t changed so possibly rule that out, maybe.
    Anyway, hope i have a male for them but it may be hard to know as they, kind of powerfeed (not overfeed) their fish and the albino’s are about 1/2 bigger than the ones left in my tank, all from the same batch.
    Mine get well fed aswell so hard to say if they just fat or females. I think i’ll try and catch them and pass them over anyway, they good freinds of mine so I don’t mind /smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” /> , you should of heard the bad language I got back from them /laugh.gif” style=”vertical-align:middle” emoid=”:lol:” border=”0″ alt=”laugh.gif” />

    Cheers Mick, crossed posts. Yes I thought the fem’s would just deposit first anyway without a male present but didn’t think they’ll survive. Hope fully I have a male to pass to them for the future /smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” />

    i’m glad it helps mate, there are certain species of corys the do’t do the T position the commonest being elegans where the female lays and the male covers the eggs.
    but the vast majority do the T.
