    Just another bit of information I just read from the Pearl Killie book by Costa. It seems the name of the locality of this population of constanciae is "Barra de São João" rather than "Barra de São Joãoo". Maybe a typing error when the person first sent the fish to KL.

    Anyway, it seems that the constanciae lives together with Leptolebias cruzi and Simpsonichthys(Nematolebias) whitei in the swamp as named above. The other endangered species from that locality would be Leptolebias cruzi as the swamp is in danger of disappearing pretty soon.

    Other bits of info from the book:
    '..There is a clear preference for rotifers and little crustaceans in L. cruzi, while C. constanciae eats crustaceans and aquatic insect larvae in equal proportions and rarely ingests rotifers."

    Tony Teiceira was the person who gave me the eggs of the Simp constanciae. I changed the name of the population code after someone living in Brazil wrote me to say I got the name wrong.

    KL, so is it "Barra de São Joãoo" or "Barra de São João"? Costa says its the latter as stated in his book.

    Jianyang,

    The guy from Brazil said it should be "Barra de São Joãoo". I assume he, being someone who lives there, should know the correct name.

    Guys,

    This one is easy to resolve... I used to spell Choa Chu Kang as Chua Chu Kang, even though I'm local.

    I did a google, with and without the extra 'O', and was pretty surprised.

    Not convinced, I tried this and now I'm confused... it's São João da Barra!!

    A Brazilian hotel chain (or hotel accomodation guide??) at this site lists the place as BARRA DE SÃO JOÃO... go figure.

    ... and who says that our fishes' population codes aren't interesting! :wink:
    I'm back & keeping 'em fingers wet,

    According to the records from the South American Annuals Group, the collection code for this fish is 'Barra de Sao Joao'.

    Ron, I've finally spotted the eggs. Just collected the peat not too long ago. was sifting through the peat using a small container of water. Found 4 round clear eggs. I guess there should be more but I'm too tired to continue. Just stored the peat in two separate containers, with one having the four found eggs and half of the peat moss and the other with just peat moss. Hopefully there's eggs in both containers :wink: Anyway, here's a short update on the pair and the eggs that I found.



    Pair spawning in breeding bowl. Couldn't get a clearer pic because I didn't want to disturb them with a close-up movement.



    Pic of the four eggs.

    Well I haven't been observing them of late. Decided to just let nature runs its course. Was pretty happy to find the eggs. Anyway I used a method to help me search for the eggs rather than find them by magnifying glass and torchlight on the peat.

    I filled a small plastic container with some water from the tank. Dropped in a small amount of the peat that was collected. The peat will break into tiny pieces when it enters the water. This is when I sift through the peat and find the eggs. Sometimes they get pretty coated up with small peat particles but they'll come out soon after. I admit, it's pretty hard to differentiate between small bits of peat and an egg but luckily I managed to spot a few. Anyway, it's pretty time-consuming so I gave up searching. Quite tired last night anyway. :wink:
