Flag cichlid, red horseface, blue pinoy angelfish & ram cichlid in semi-blackwater aquarium - part 3

Part three of flag cichlid, red horseface, blue pinoy angelfish & ram cichlid in a semi-blackwater aquarium. A dead oak branch has been crammed in, after a long time being unhappy with only the rocks and driftwood below. The fish kept destroying any live plants. Somehow they even ate all the duckweed. Low maintenance 4ft tank with simple internal filter and occasional water top-ups. Bizarrely, the lights originally caused a video 'banding' problem, so I had to use a small reading lamp, which did not cause this issue. After putting in the oak, the water is slightly cloudy but I find that using Seachem Pristine and a small Purigen bag is all I've needed over the years with various setups. I hope this inspires someone. Enjoy!
