The plant arrived quickly and was in good condition. After washing the gel and part with your fingers, I got the part in the gravel plugged in and one of them directly to the disk, so I can see how fast it grows. Initially, there were many dead leaves transparent but then disappear with time. However, it takes some time until it spreads, but when it's finally time does it pretty fast. For a 23L tank, but I would at least 3 order!
