  1. http://www.aquaboards.com/viewtopic.php?pid=32547

    It's possible that it may not work because the trimming removes the hook part of the gynopodium that the male needs to secure himself to the female vent. It may also be the case that heterozygous (HH) high fin genes are leathal to the developing egg.

    When I was trying to breed my Lyre Tails I decided to get a high fin male and use him, like th eone in your pic. But it so long to find one that one of my females changed sex and as it was developing its gynopodium it fertilised the other females and I ended up with all the variants of Lyre Tail, High Fin, and normal swordtails.

  2. now the next question how do you know that it is too long to reproduce???

    With the Lyre Tails the gonopodium becomes corkscrew shaped at the end.

    If you don't want to circumcise your fish, you can get a high fin male to cross with the lyre tail to give a good proportion of lyre tails.

  3. I'd like you to share your opinions and experiences about Green Severums and Severums in general please.

    I'm in the research phase regarding adding a large fish to my 5ft tank which is relatively tall and has a volume of 300L.

    Current residents:

    2 Angel fish (males)

    Bristlenoses (most are quite large)

    Clown Loaches

    YoYo Loaches

    Kuhli Loaches

    Plants:

    Java Fern, windelov

    Tiger Lotus

    Crypts

    Indian Fern (large leaf)

    Cyperus helferii

    Thanks in advance :D

  4. I've found with Royal Whiptails, Sturisoma festivum, that you need to have a relatively dirty tank because the fry feed on microscopic critters in the muck. You still need to do water changes but don't vacuum the bottom. I don't know if Red Whiptails are the same but I wouldn't be surprised.

  5. HFF hollywood Fish Farm - the Only place to go when in aucks IMO

    esp monday /fridays coz it keeps dave busy and i like seeing him work

    :lol: Yep another vote for HFF. I find that Friday afternoon is the best because they'll have the stock for the weekend in, and you can have a chance to buy before the weekend crowd.

  6. Soon after we get the anopheles mosquito, the adult female of which is the vector. There will be people in NZ with malaria that they have contracted overseas but no vector at present to transmit it person to person. Regular checks are carried out around International airports and ports for introduced mossies.

    One of the tasks I'm involved in is the weekly mossie checks. The surveillance program checks sites up to 4 km away from the terminal looking for foreign vectors and breeding sites. Some of these vectors travel only 400m in their life time.

    Murray Valley encephalitis and Ross River virus, have vectors present in NZ as does Yellow Fever and Dengue Fever. But the chances of someone coming into the country with one of those diseases and being bitten by a mossie that then goes on to bite someone else (i.e. you) is very low.
