Decided to rescape the tank, i created a wooden "wall" in the background out of 3 types of driftwood. Despite fixing the wood on the back glass there is still plenty of room to swim in the back. Also i plan to add all kind of anubias plants in the cracks and spaces betwen the pieces of wood.
Added a small area with riverstones for the hillstream loach. Also Mr. Pleco loves the new cape. so do the Panda Cory. Also this way i have the front area free to enjoy the fish swimming.
I do plan to add some Crypts, a hydrocotyle mini and a Lagenandra red. And if the Pogostemon won't grow properly i'll replace it with a Hygrophilla Compact. I like how small and compact the Echinodorus grisebachii 'Tropica' stays.
Got a second light for the tank. The 1st one has Red+Blue+White. The second one has Red+Green+Blue+White. Both are made from aluminum painted black , with plexyglass protection. Made by the same polish company. The lights have a timer and 9 stages of intensity.
