Hello michael and rich, thanks for the suggestions, i do notice one or 2 of them i kinda feel that they are males from their size difference, hmm cadual extensions,, i'll take a look and see if i can tell the difference, I have the Aqualog SA II i believe and if i remember last time i looked at it there are specific pictures of a male and a female, but i couldn't really tell the difference, I'll pull out the book again just to take a look to see if i can tell in the pictures, the reason I'm asking about the sex is I would like to take a pair ut of my community tank for breeding but I don't want to place 2 males into a 25 gallon and then find out then i come home from school and work that one's dead = ( thank-you for the suggestions, any more would be apperciated but I'll definitely look at these 2 comments Raymond Wong www.sfu.ca/~rww/Aquariumstart.htm ----- Original Message ----- From: "Michael Brock" <michael@fun-da-mentals.com> To: <apisto@listbox.com> Sent: Wednesday, February 21, 2001 3:56 PM Subject: RE: Bolivian Rams > I have a great deal of success sexing my Bolivian Rams by their size (my > mature males are a bit larger) and the length of the caudal extensions.
