I spawned mine in ph.5.4 and 10ppm. hardness.I think they would spawn in a higher ph.than this as they were one of the easyer apistos I have spawned.Has anyone noticed the growth rate for these fish?Mine are growing at a phenominal rate.They are about 2 months now and I have norberti that are 3 months andsome of the hongsloi are almost twice the size.I have never seen a apisto grow so fast.
