Jordy, your plant list must be commented upon in many respects. I confine myself to
“crypto soorten”: Most commonly used aquarium crytos are Sri Lanka species. They live in water totally different than that for Paros. It is a science of its own to develop a method of keeping those fish together with cryptos of the black waters. It is nearly impossible, a matter of different structure. Better, you leave cryptos out.
As the other plants with a great foliage are concerned you must mind that they all live form nutrients dissolved in the water. But your problem is to keep your nearly nutrient-free water blackwater as stable as possible. Using nutrients for plants is out. I don’t see a solution. Of course you can have a green tank with Paros (mine are green too), but mainly with Ceratopteris (very good) and other swimming plants and an occasional rank of Ludwigia or Hygrophila. But the lower your pH the number of suitable plant species is reduced to few. And for some Paros you need pH of 4, even of 3.5. The main aim is to reduce germs which attack the eggs and the larvae. Therefore you need the low pH. Plants are possible only with compromises, pH 6 – 6.5 for example. But the normal planted aquarium is an underwater-garden run with much carbon dioxide, and the Paro-habitats are not of that kind. Paros live within the riparian grasses that hang into the flowing water; that’s different.
Nevertheless, your tanks could be full of green and look wonderful, as do mine, but forget the normal scheme of gravel and underwater gardening. Amano is nothing for Paro-lovers (to name an extreme example) Even a Holland-aquarium (as we call them in Germany: heavily and nicely planted tanks with many plant species) are not suitable and practicable. It’s for show not for use. At least not for keeping and breeding Paros.
I wish you luck with your experiments.
