rastamon34 Posted December 26, 2021 Share Posted December 26, 2021 (edited) So I’ve bred thousands of guppies and acquired these ribbon tail Japanese pingu guppies, they are gorgeous, albeit a little fat. I originally bought 6 of them and one was pregnant and had three or so fry survive. Anyways, I know on some the ribbon tails can interfere with breeding, but I have a mix of a male with no ribbon and 2 females with no ribbon. So out of the 9 or so fish some combo should bang? I have no interest in punnet squaring the traits of ribbon, but I cannot get these to go for the life of me. I’ve had them in a heated ten gallon alone, now have them in a room temp about 70 degree planted 55 with some precox and Cory cats. I’ve had these guppies for almost 9 months with no breeding. I’ve got koi guppies in the tank below with more babies than I know what to do with, I’ll toss in a pic of the prolific male, but can’t seem to get a single female holding here!

Fish Folk Posted December 26, 2021 Share Posted December 26, 2021 Best wishes… I’ve no clue how to pick that lock. Your set up looks amazing! Wow those males are stunning… Link to comment Share on other sites More sharing options...
Chris Posted December 26, 2021 Share Posted December 26, 2021 Sounds like you've certainly bred more guppies than me, but aren't there certain strains of guppies/livebearers that have modified gonopodiums that makes it difficult/impossible for a male of that strain to mate? I can tell if the gonopodiums on your males are abnormal, but I know I've read about that particular issue somewhere. Link to comment Share on other sites More sharing options...
Beardedbillygoat1975 Posted December 27, 2021 Share Posted December 27, 2021 In this case I do believe you’re correct - since you received ribbon and ribbonless males the ones without ribbon will pass on the ribbon gene and breed. The ribboned males typically have an elongated gonopodium making it impossible for them to breed unless you clip or circumcise them which is super risky. Glad the breeder did the right thing and gave you some ribbonless males. Link to comment Share on other sites More sharing options...
rastamon34 Posted December 27, 2021 Author Share Posted December 27, 2021 Right I figured with a combo of non ribboned males and females someone was bound to get pregnant. I guess not though. I’ll Give it a bit more time but I don’t know how I feel about a non breeding group of 8 9 fish taking up my whole 55. I’ve had other guppy colonies turn into hundreds in there, I think these guppies may get demoted to a smaller tank Link to comment Share on other sites More sharing options...

If I recall correctly it was D. Grey and he was talking about using 5g instead of his usual 10g, but I can't swear to that and I can't dream of remembering which video, I've watched too many. 1 Link to comment Share on other sites More sharing options...
rastamon34 Posted December 30, 2021 Author Share Posted December 30, 2021 I think I will move them back to a 10 gallon. I want to display them, but also they are wasting the space I could be breeding dozens in the 55. Link to comment Share on other sites More sharing options...
Levi_Aquatics Posted January 8, 2022 Share Posted January 8, 2022 Ribbon fin males can’t reproduce but since you have a regular fin male you should be good unless he is sterile. Link to comment Share on other sites More sharing options...
rastamon34 Posted January 24, 2022 Author Share Posted January 24, 2022 I’m starting to think the regular male is sterile as well, moved them all down to a 10 gal with some Indian rice fish and yellow shrimp. Took a scoop of 50 or so koi guppys and moved them on up to the 55 gallon. Seemed like wasted space to have a non breeding set of 7 or so guppies in a 55. I think I’ll give it another month or so , before I throw either a koi guppy male or dumbo metal head male that’s proven his skills in there to shake things up and just see what happens. Don’t quite have the extra tanks at the moment to selectively breed, but at this point I’m curious what would come out! Link to comment Share on other sites More sharing options...
