I try new plants regularly, and most do not survive. But when they do I leave them there. In such a way I composed some tanks with mainly cryptos, Java fern and Ceratopteris. Most cryptos do fine here, even in really dark water. I also found Sagittaria subulata does well in every condition I created. From highly acidic blackwater to room-temperature with a lot of light. This plant will make nice lawns with a lot of space beneath so that paros can hide under it.
