Saw some gorgeous guppies today, but wouldn't bother getting an actual trio if the male couldn't breed.

He had an elongated fin down below. I am not sure if it was his pelvic fin (as in my thread title) or his actual gonopodium. Am I right in thinking its probably his gonopodium and he would be infertile? He was gorgeous, there were a few males I saw that had elongated fins.

A lot of the fish with the extra long fins can't do the deed :-?

Rumour has it you can give it a wee snip a little longer than a normal guppies bits stick him in a nice clean tank with some meth blue and let it heal and then it should work

How long are we talking about?

Keri Anne has a lovely swordtail that has a gonopodium that drags past its tail (the shorter part of the tail, not the sword bit) that cannot 'do the deed' - I have offered to 'fix' the problem for her with a scalpel , but she's too squeamish to let me!

mmm, snipping would just be so hard, they are so tiny! Probably end up stabbing him in the stomach with the scissors

Hes probably nothing special. Was entirely yellow/gold with an irridescent/pearl leopard pattern which I thought was gorgeous.

I stole a pic from the net and drew in (can you tell? hahaha) his long fin:

cesarz where are you lol? I haven't tried breeding these yet, but it might be in the genetics that the females carry the genes for these, then they are passed onto the male fry. At least that would be a way to do it without surgery.

Rozki,

was he like this:

Pretty much. Your photos looks like my drawing

Was just hard to tell as he was at the back of the tank trying his darndest with a missus :lol: So couldn't see if it was a plain tube, or maybe a bit more, but yeah, what else could it be apart from an elongated gonopodium?

the gonopodium is basically a hollow tube

this reminds me of the jacobin pigeons and their long feathers, they can't breed without having their feathers trimmed

He looked pretty much like this...

Plus his trailing whatsit

They can breed when the elongated anal fin is a hollow tube , and can be cut to the proper length. But if it does not form a hollow tube, it cannot breed. When the elongated gonopodium is cut to a certain length, it heals into a functional one. better to find a female to breed with instead because they carry the genes too.

cesarz, I bought some guppies today. Only males though, as I'm not breeding them anyway. Got 2 of the nice gold leopardy ones, one of which has the long gonopodium.

Photos are up in my planted nano tank thread in the Freshwater section. I like the golds, but partner got to choose some too, hence the random other guppies

Cesarz is up here at the moment, saw him today

Don't know if he has internet access where he is staying.
