What's the best way to differenciate those females ? Would those interbreed (a male agazis with a female cacatoo by example) ? BTW: Rams should learn to read, I got a couple that lay eggs on a stone, not in gravel... another couple prefered gravel in the same tank. Guppys should reads books too, they would know that at pH<6 and very soft water, they should not give me so much childrens, they are WAY much more productive than my other tanks (high hardness). And it's incredible to see that rams don't even try to eat those childrens ! ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
