Your tanks are decorative but not characteristic or specifically designed for the needs Parosphromenus. It’s your needs (or our needs): the wish for an underwater garden.
It’s a compromise between the needs of our fish and our own preferences. In such a tank you can keep Parosphromenus, of course, but you can hardly control the breeding and feed the young fish in their first weeks without overcrowding the water with too much small food. Most of it will decay and worsen the milieu.
And such a tank will function with some hardy Parosphromenus only that will do with a pH not much below 6.0 (that is e.g. linkei, paludicola, quindecim, partly nagyi. Mind that the optimum milieu for all that species is a pH clearly less than that, mostly we found one between 4.0 and 5.0). Most other species will not thrive in it at all and will hardly find their best live coditions, however. They will live for some months but age more rapidly than normal. Most aquarists don’t see that because they are no longer used to keep fish for longer periods. But these fish are endangered; one should decide to keep and breed them under the best conditions their physis is adapted for.
A typical tank for most Parosphromenus species must bear a lowering of the pH towards 5.0 and lower, often even below 4.0, and must contain waters without any calcium. The plants I see growing very well in your tanks will not stand that. Mind, our fish are animals adapted to peat swamps!
I can understand your wish for a decoratively planted tank, it’s a wish of my own too. There are some plants more adapted to that, but I can hardly see them in your tank. So, I suggest to have not only one tank but at least two or three: those in which your fulfill that wish, perhaps with linkei or paludicola, as a compromise, keeping them not in their optimum milieu but in a milieu they can stand for some months, and others for the most Parosphromenus, more adapted to their real needs and natural habitats. And easier and more safely for feeding the young.
