 | Idiot Guppy question |
Mogmog  Hobbyist Posts: 74 Kudos: 66 Votes: 2 Registered: 03-Sep-2004   |  I'm trying to make sure I have a good male:female ratio for my new tank (Guppies of course) But I'm having a hard time being able to tell the genders apart. I know males have the modified fin, the gonopodium, but I have no idea how to tell it apart from the normal anal fin. I've also heard conflicting opinions about whether the males or females are larger. Ack! (EDIT: I'm just realizing now that I should probably have this in Livebearers Lane. Sorry. @.@) [span class="edited"][Edited by Mogmog 2004-09-04 16:14][/span] |

| Mike R Fish Addict Posts: 593 Kudos: 830 Votes: 322 Registered: 27-Jul-2004 | The gravid spot is another good way to tell. If you see a dark area inside the fish just in front of the anal fin it is a female. Have fun, Mike |

Racso   Mega Fish Some Assembly Required Posts: 1163 Kudos: 1442 Votes: 35 Registered: 19-Feb-2002  | The gravid spot doesn't always work as some livebearers have blotches all over their body, and they may just have one at that spot. Also, some livebearers have black bodies (such as half black guppies) and that cannot be seen. The only true way to tell is by the anal fin: triangular for a female, tubular for a male. |
