Wanting to do a pair of apistos in my UNS 40C it’s a 16 gallon. 15.75x15.75x15.75 cube. Good amount of wood and rock to create a lot of hiding. Will have dwarf sag, crypts and red root floaters for the planting. Tank is cycled and currently no stock to it. Was thinking a pair of apistos, chili rasboras and Otos. What recommendations would you make for the pair? This will be my first time with apistos.
