The 'mystery Apisto' i bought have finally coloured up properly and are definately Apisto atahualpa. They are more orange than the pictures on the Krib site but otherwise v. similar. I think they have spawned - the female is incandescent yellow with black pectorals and seven black dots along the base of her dorsal, she is guarding a 'cave' - well more of a 'chimney' actually - a 9" tall plant pot with the hole enlarged. - The male is providing perimeter defence. The reason i'm posting is that i saw the male gather frozen bloodworm from the middle of the tank and swim 18" to spit it into the cave containing the female. He did this several times, so it wasn't just chew-spit feeding as some Apistos do - has anyone else observed this kind of behaviour between ADULT fish? The comments on the Krib about atahualpa being aggressive are valid - it doen't help that the strongest response is to orange and yellow fish (i.e. all female Apistos). I have 2m 3f as the only Apistos in a 42x17x17" 'jungly' planted tank with Cardinals and they seem ok - in anything smaller sub-dominant fish were 'up behind the filter' Alan W ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
