I thought of something that might be worth considering. At fist I thought a "super guppy" may have been some other type of livebearer. Back in the day they sold many livebearers that they do not anymore. I looked up profiles on guppies and some older information out there says they get up to 3"... but I have never seen a 3" guppy. Older information on guppies, say from the 60's and 70's, lists guppies as one of the most hardy fish with huge broods. This is no longer true now. Guppies have been so inbred that they are a shadow of what they once were. I read that they rarely reach the SIZES that they used to or could in the wild and that they have smaller broods. So my theory is that maybe the fact that most of our fancy guppies are so inbred now and infiltration of so much inferior stock has made super guppies less likely?
I have actually had 2 inch females in my tanks, I think the main reason we do not see fish of this size are 3 things, 1. Tank size, 2. water quality and 3 over crowding.
The average fish keep will have their tanks filled with fish in a small tank, we all have done this at one point or another. Due to this, the water quality will lower, from lack of proper water changes. This eventually will stunt the fish and they do not grow past their prime length.
Plus many people dump salt into the tank to "Tonic" the water, which in turns shortens the fish life spans.
But as for these Superguppies, I believe they were a morph created by one or 2 breeders who may not be in the business any more. Once these breeders left, we no longer saw these giants and due to the conditions I made mentioned of, many fell victim to poor care. I am sure if you looked around, there are probably some show guppies with these traits but you will more than likely pay for them. I remember seeing some Huge yellow females about 5-8 years ago. But since that shop closed, I haven't seen them any where else. So they may have been from a private breeder around my area supplying that shop.
So if you are interested in them, I suggest either checking with your local fish club, bound to be a local breeder with fish like that. Or, check around and find some breeder online who may have this morph/strain in his collection. Good luck but this strain might be extinct already, except for the few rare giants we see every now and then.
