    Hi guys.

    I bought 2 discus from guppies 4 yuppies in Oct06. They were part of last years inport stock (Leopards)Their sertificates were dated Jun06 so by now they must be about 15 months old.They turned out to be a pair.However the male is still shooting blanks. They were about 4 inch when I got them and have spawned around 30 times. The male is very attentive during spawning and vigorously 'fertilize' the eggs.Since bringing the pH of the water to about 6.5 the eggs stay healthy for 3 or more days but still infertile.

    I have put a new female on loan from Peter(thanx Peter) with him about 3 weeks ago. They had their first spawn Friday but same story as before.Hoping my origional female will spawn with one of Peter's males and produce fry.

    My questions are:
    1) Does any one else have stock of the same inport and are those males fertile yet?
    2)How much longer should I keep trying to breed with this male before clasifying him infertile? :crytear:

    Here is a pick of the latest action.

    Hi Smallfry,

    May I know if you've confirmed their sex by their breeding tubes? This is the best way to make sure that you have male and definitely a female. Otherwise, may I ask you a few question so that I can have an idea what's going on.

    1. How often do you see eggs being laid?
    2. Does it always be on the same spot of the cone?
    3. What is the pair routine feeds and husbandry?
    4. Water parameter that the pair had been raised up in and current breeding tank conditions.

    Hope to be able to help you here. Thanks.

    David

    Why not try and hatch the eggs away from the parents i.e. to tell whether any fertilization has taken place.

    Hi Guys

    With regards to questions by David :

    1)Once a week
    2)Different places ie drift wood, spawning cone etc.
    3)Feed one to four times per day.Always frozen turkey heart/seafood mix then some bloodworm( live or frozen) or tetra bits or live mosquito larve(BIG FAVORATE) or arthemea(frozen).
    4)Water peram. as per Tetra 5 in 1 strips
    NO3 (Mg/l) = 0
    NO2 (Mg/l) = 0
    GH = <3d
    KH = 0 - 3d
    pH = 6.5 - 6.8

    They are breeding in the tank they were raised in. The only thing that I changed is the pH(added Phiedmoss).It used to be 7.8. The last few spawnes with the origional pair of leapards was in the lowered pH of 6.5 - 6.8.Although I could see that the eggs stay healthy for longer(no whites for at least 24h and no fungus) not a single developping fry either!

    The male has grown a long tail of about 2cm on its dorsal fin about 11/2006 to 01/2007.It has a much shorter and thinner breeding tube than the female.

    This is a pic of the male

    Certain strains take longer to mature like "true"

    Hi Peter

    Welcome back! I was starting to feel very lonely with every one else away for the long weekend. :wave:

    I guess you are right. But it is very frustrating.I think I must go visit William and try and find a mature male since the female is more than ready. :)

    lol....your Female is still turning her nose up and not interested in any of my males   :scratch: but she's enjoying the 5 course meals.   ;D

    Maybe consider, to let your pair continue to bond with spawns and in time they will get it right and surprise you when least expected. Hang onto my female if you want and get another male of similar colour and hopefully get you off the mark? :thumb: maybe some juvi's inreturn   ;D

    Hi smallfry

    Just wanted to share on this spawn of SRW (Spotted Red Whites), which also come from David. Saying in their own time they will spawn...but lol...we just have to wait a little longer for the Leopards

    They became free swimming early this morning, the only problem, they battled a bit to find the brooders from some distractions. (which where removed) anyway, I’m pleased as pie...

    Hi smallfry

    I hope you don’t mind if I continue with my updates on your thread.

    Well....the were some complications. The survival rate went down....to my horror....and then ....they wanted to spawn again and the fry were been eaten, so during this tense nail biting stuff...lol, I was able to catch the last 13 (less grandkids to spoil) and put them into a one foot to hand-raise.
    They spawned again.... Sunday late late and should get wrigglers tonight...but will count the chickens after they hatch...lol

    First time to have white fry

    I saw Peter's setup again over the weekend, and once again it blew my mind away with how great it looks... Well done Peter, you are certainly one of the most pasionate fish keepers i know, and your setup is just amazing! Cant wait to see how you progress on the breeding of your "kiddies" in all those tanks
