Hello Joel, Whats a fellow UNYKA guy doing raising apistos? Glad to hear that you are though!! If you managed to raise killies, you have the right kind of water and live foods necessary to raise apistos. Most like nice soft slightly acidic water. The Cruzi, Eunotus and Cacatuoides can handle slightly alkaline water, the Nijsenni on the other hand like the water really soft and fairly acidic. I did best with these guys when i had pH of less then 6.0 and really soft water. Feed lots of live foods, they all love that. Frozen bloodworms, white worms, daphnia, baby brine shrimp and occasional black worms, Oooops, here comes a ton of dont feed them black worms, lol, but i did for several years when i could get good worms from Howard. I dont use black worms any more because of my convience. Not because they hurt my fish. Never had that problem. Most of the fish you mention will do fine in harem spawning situations except for the Nijsenni. I found them to be strictly pairs only fish. The odd fish out would get beaten very badly, even to death in most situations, so go with pairs of Nijsenni. Clean water, just like with killies, is a must for all apistos. They dont care for poor water qualiity. Joel, if you have any questions, you can always email me off list . Always glad to talk apistos!!
