To take a different route here.
I couldnt keep Apistos alive anytime I ever tried them for whatever reason. Water would be ideal, temps werent an issue, planted tank anything else in the tank would do great.
Last chance/attempt, I picked up 2 Apisto Borelli's to decide once and for all if I could in fact keep them.
15h, medium planted, Fluval 105, inhabitants are 12 CPD and possibly a few shrimp.
2 months later, the Apistos are alive and seem to be doing ok.
