So I have this 140 blackwater setup that contains 10 cardinal tetras along with 8 catfishes of two species Corydoras duplicareus and Octocinclus and 6 marbled hatchetfish.
The plants are doing quite well so far and the aquarium is an absolute delight to look at especially in person because there is actually roibos tea in it that makes the water look tanned because of tannins although you can't see it in images.
Really the only things I want to add now are a pair of german blue ram cichlids,along with more plants and possibly more dried oak leaves for that natural look.
The final touch for me though would be to add some sort of plastic/ceramic decoration like a skull or something like that although it still has to look natural to fit into that blackwater theme.
What are some great ideas for decorations that might work in your opinion?
