  1. His spine is not grossly bent but enough to notice that it's not straight. looks like a little humpback.

    He is okey to use as a breeder then, he is like that due to his large tail, try choosing the female with the thickest peduncle so that the next generation is strong enough to carry the tail horizontally and not get dragged by it which results in this kind of bent spine.

  2. The best bet to have a Red Tux offpring is with the fluoro/neon blue tux female, you will get good red tux as well as neon blue tux.

    The tux girl with plain tail will give you red tux as well but not as good as with the neon blue, the others will give you a dull red tux, anyways as what SamH says,there is no harm in trying them all.

    You mentioned that you wanted big tail fin, the only one that will give good big tail in the first generation is the female with the widest tail, so choose that one whichever it is.

    Depending on how bent he is, he might not be able to do the job. Is he bent down because the tail is heavy or does he have a crooked spine?

  3. Is there anybody importing aquarium plants at the moment? All the people down here who used to import plants flagged the idea a long time ago.

    I have been actively legally importing plants and it is very easy as long as you follow MAF's strict rules. But these plants would never harbour hitchhikers because they were cultured in the lab.

    Sorry guys no shrimp eggs.

  4. My guess is that most of those plants would not be very suitable for the average aquarium in NZ.

    Yep you got it right alan, I participated in NIWA's trial and the only ones left are Glosso elatinoides and the ranunculus. All the rest died out. These plants could be further selected by subjecting several accesions of the same species from different sites and subjecting them to average NZ aquarium conditions and see which variety survives.

  5. I have miniature marginal orchids and epiphyte orchids if you want some. I would also recommend miniature bromeliads of the Tillandsia family. Also small leaf pelleas will be good as marginals. Miniature peace lilies(Spathiphyllum), small ferns, carnivorous plants, miniature trailing african violets( I have some), mini hosta, and anything that can take high humidity.

  6. Yep, definitely.

    Most occurences are females changing to males, these are called XX males and is a tool used by Asian breeders to produce all female guppy offspring. This phenomenon, as Simian has pointed out, occurs in female only groups.

    Males changing to females are usually sterile and also a technique used by Asian breeders so that you cannot have any offspring from the good stock that you just bought so eliminates competition.

    Another technique they use to change guppy sex is subjecting them to hormones of the opposite sex, male introduced to female hormones and females introduced to male hormones.

    Our aquarium fish population for trade is not big enough for this kinds of tricks and hopefully it will never come to this.

  7. is this a young lyretail? can't quite see the shape/pattern of his tail but I believe it is.. it's the one I took back to petshop.

    Bikbok,

    Sorry your one is not a lyretail, the ones on the thread's first photos are.

    This one is a lyretail: the tail looks like a lyre or a harp
