"Siestas help control algae, especially in tanks without CO2 injection."2-4 hours for a siesta is something I've seen Diana mention frequently. On page 179 of the Ecology of the Planted Aquarium (we need a shorthand for that) the benefit of a siesta appears to increase linearly over the 4 hour period.
The nomenclature can be a little confusing. I'm still not sure when a lily is a lily and not a lotus. They both grow pads and can look remarkably like each other depending on the individual coloring of each plant. My tiger lotus recently sent out runners that resulted in new plants. The new plants already had small bulbs attached to them by the time they were big enough for me to notice their existence in the tank.I'm not sure about the growth under the substrate, I haven't poked around. Six weeks ago when I planted it, it was just a plantlet with a few roots. Do you have any idea how long it takes for a lily to grow a bulb?
Yeah, my brief wikipedia search reveals that nymphoides are a definite thing. We're most familiar with the nymphoides aquatica a/k/a, the banana plant. There are dozens of other species found all over the world, many of them considered invasive.I see. Looking into their taxonomy on itis.gov, the genuses Nymphaea (your lotus) and Nymphoides (my lily) share a class, Magoliopsida. They are in the families Nymphaeaceae and Menyanthaceae respectively. From a few minutes of reading, it seems like your lotus is in the true water lily family, whereas my "lily" is an imposter. Its genus Nymphoides was named after its resemblance to Nymphaea (water lilies).
I haven't found anything yet about the differences and how to identify them, so if you happen to, I'd love for you to share.
