Hello, May i suggest to mix the two males (and females), thus giving them sexual competition. You can also have them in two contiguous tanks each one in LOS of the other, it might be less physically dangerous. Maybe they are young fishes too, which have to become a little older, wise, and sexually mature. Females are ready sooner. (No anthropomorphism in this ;-) ) I've really seen comportmental change in the parental care given by my "Moliwe" mâle between two spawns within 5 months. He is now wiser than before and is now fully adult too. My .2 Euro. I've just spawned my P taeniatus moliwe pair with part of their precedent brood in the tank. I won't do this again, because the juveniles are the most efficient predators of their little bros and sisters. They share the same part of the tank, darting off whem the parents chase them, but their's allways a little one sneaking and lurking. The other dithers are A australe, D rerio, H axelrodi, and they are very well put under control by the parents. Colin DUJARDIN PS : I'm seeking for a vinegar eels strain somewhere in Europe. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
