Hi i'm new to this site just registered and as i was reading this i thought about asking this question. I am breeding guppies at the minute and hoping to keep it to just guppies in the tank but when i get to many babies and no way to get them to a shop before they grow to big to be in the fry tank, i give them to my friend. She puts them in the floating breeding box and when they are big enough she puts them in the big tank with her others, but i have noticed when i have been round a couple of times that most of them are deformed and they were fine when i gave them to her. They seem to have tails that instead of going straight along like they should they bend to the right and it looks like it could be painful for the baby guppy. Please tell me whats happening to them.

i understand you have a question that needs to be answered and i dont mean to sound rude but next time you should post in a new topic because ive noticed you do this alot.
and im not sure how to help you in your awkward predicament. id GUESS that it was just a birth defect that wasnt as visible when it was smaller

just want to add my two cents about the conjoined guppy fry. while some birth defects can and do come down to poor conditions or general health of the mother, conjoined fry are not environmental or genetic-simply a developmental issue. what happened is one embryo, for whatever reason, while developing split into 2 (think about identical twins in humans-same concept). HOWEVER, it did not separate completely, leavening the 2 fry "stuck" together (same as conjoined twins in humans-there is little knowledge about why this happens even in a human sense). so basically, conjoined twins in any animal is a DEVELOPMENTAL abnormality with very little understanding of why this happens. so really, there is no point debating that aspect. other defects are definitely down to inbreeding, which is why it is important to add "new bloodlines" every so often. but the conjoined twin fry are just one of nature's oddities. consider yourself fortunate to have seen it. i think it is very interesting, although may not have survived even under the best of care.
