Apistogramma biotope tank

I tried to recreate apistogramma biotop in my 60l aquarium. There is still no apistogramma fish in the aquarium but I plan to put 1m and 1-2f of apistogramma agasizzii or apistogramma cacatuoides. Now in the aquarium swim - 3 corydoras aeneus, 3 ancistrus sp (2-3cm long) and 8 glowlight tetras. Sand 0,3-0,6mm, stones, mangrove tree, oak leaves and branches from grape vine (Vitaceae.).
