hi theres two plants. i know theyre aponogeton. i thing the first may be crispus but im not sure on the second. the second is the on with the bud on it thanks!
looks like my crispus for the leaves, but the flower stems on crispus dont split into 2, they send a single one up, (well mine did), theres quite a lot of hybrids out there as well apparently
also the leaves of crispus dont float on the surface, they might to with hybrids and other species though
It's not ulvaceus. I have it and the leaves are way broader and look totally different. It could be crispus but mine hasn't flowered yet so not sure. My cirspus leaves are more wavy on the edges though but that may depend on the tank I guess.
