Ok, my altispinossas are about 1.5 inch long now, they have a vent sticking out near the bottom of the fins, how do you sex these guys? i have a pic of a couple of them from 3 weeks ago at: http://www.geocities.com/Heartland/Estates/5060/fish/fish.htm if someoen can tell anything from that. You can just barely see teh vent, looks like a ltitle dot, on the pic on teh right side One of them has a very pronounced yellow portion of its body. I read in Loiselles book about the biotodoma cupido, all he had on sexing them were that the females tend to have small iridescent spots instead of lines under their eyes! hard to tell. All these guys might be too young yet to tell. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
