    All that glitters...

    When it comes to selecting fish as potential breeders I find it really helps to look for negatives, "That ones got a misshapen fin", "I don't like the body shape of this one", and so on. I find taking this negative approach makes it easier to part with fish.
    About a year ago I was sorting through some "Manu Nanus", my nickname for my silvers that have both Manacapuru and Rio Nanay fish in their their bloodline. There was one fish with a fair amount of glitter, but it was markedly smaller than most of it's siblings, so I took it to my shop and almost immediately regretted my decision. So instead of going on sale, it went into a display tank where he's been ever since. Over that time he's grown but is still very small for his age, but despite his size, or possibly because of it, he's a feisty and belligerent individual, not afraid to take on others much bigger than himself.
    I took these photos of him a couple of days ago....






    ...and have subsequently decided that with that much glitter, it's worth seeing if I can pair him up with a good sized female and hopefully get some better sized offspring which retain the colouration. So he got a reprieve and came home to a breeding tank.

    Given his small size and aggressive attitude, I've named him Napoleon.

    As an aside, has anyone else noticed a correlation between size (or at least growth rate) and guanine production? Paraibas for example, in my experience tend to be slower growing than their non paraiba siblings, and I get the impression that those with the best colouration tend to grow the slowest.

    ..pretty angel....as for size....my Rio negro crosses produce some smaller females...but the males seem unaffected in size.....the females do seem to have more glitter coverage.....so I think you may be on to something....

    ..but the F2's have much bigger females in comparison, and very good glitter coverage is retained.....?.....the crosses were to Manacapuru's....

    He attacked everything in life with a mix of extraordinary genius and naive incompetence, and it was often difficult to tell which was which.

    This is definitely a male, his breeding tube was down the other day.

    Sadly not yet. I tried him with a couple of different females and both just beat him up. I'll try him again when I have a suitable younger/smaller partner for him.

    The problem is I have far too many potential breeders, and far too few tanks to put them in.
    He has put on a bit of weight though, so I will try again soon.

    I've paired him with a different female and at least they're not fighting, but no eggs yet.
