I think your tanks are really beatiful and pleasant to look at. Especially the first one with the unidentified females, – what a pity it turned out to be four female. I think you could add a few boraras now that it isnt going to be a tank with fry. Its gives a bit of life and the paros dont mind it – might bring them more out.
The tank for the quindecims, I wonder, do you not have a background ? I think the paros will not appreciate the fact that there is light coming from all sides. Is it standing in the window ?
I think I would put some dark, black paper on at least one, maybe three sides of the tank.
But I like your setups, think they are inspiring.
