Thanks Raul.
There actually are some E.martii's in the back right side, but I can't get them high just yet.
I always thought the swords on the right are uruguyensis while on te left are two horemanni. The left ones are very long leaved with soft leaves and no pellucid lines and has never in 5 years produced an flowering shoot, on the right side have leaves app 1 yard wtih raised and hard veins, no pellucid lines, and produced a flowershoot after a few weeks already?
I will change the tank by adding quite a few stem plants in the next week. I will reduce the Hydrocotyle for it, and remove the myriophyllum. they don'tgrow very well. (among others Tonina, Alternathera, Cabomba, Heterantha, Ludwigia)
