Thanks mate, the comments are much appreciated
The back is actually pretty well lit this pic was just taken with the lights turned down to the lowest setting as the photos end up pretty saturated with it up full, I really need to get a few better pics rather than a quick update as my terrible quick phone pics don't do it justice
I added 8 celestial pearl danios at the weekend, with their already being 8 espei rasboras and the betta, fish are split between all levels now so actually have more space than it sounds
Funny you mention about the reds, I'm thinking about ordering either Rotala Rotundifolia and Limnophila Hippuridoides, while I'm not expecting to get much reds at all from my low/moderate lighting it'll be a good test and learning curve, maybe an anubias nana on the wood as well then I'm done for now
The hygrophila salicifolia isn't really doing it for me in the back right corner
