Last day of salt today. Sid's fin problem has halted for sure, and reversed in some places - but not others. His anal fin is showing less sign of repair than his tail, which had the rapid rot and now is showing plenty of healthy new fin growing. The anal fin has a bite-sized chunk out of it, which bothers me. I assumed it was the rot, as I watch him quite closely and have never once witnessed fin-biting. But at least there's no more loss.
I'm keeping him (against his will) in the hospital tank until his main tank settles with the new wood. It's still at 0.25 ammonia or thereabouts today, though the test was more yellow than pale lime, so perhaps it's dropped a little. I'm leaving Sid be, in case the changes threw the other tank into a mini-cycle or something (rather than it just being that I overfed the tank..).
My wisteria has lots of lovely new leaves coming on. The crypt in the ceramic pot is looking a tad pale, and its leaves are long.. it's a longer-stemmed variety than some crypts and it's producing pups okay. But I wonder if it's getting enough light to be happy.
And I think I found out what the "freshwater seaweed" is! It looks like this:
Which is often sold as 'Pellia', 'Pelia', or 'Subwassertang':
(German spelling: Süßwassertang
) is a type of aquarium plant formerly known as "round Pellia" or "round-leaf Pellia". It was long considered to be a liverwort, which it strongly resembles, but in 2009, a molecular phylogenetic study determined that it is, in fact, an fern gametophyte. Further, it is a species of Lomariopsis. It is closest to Lomariopsis lineata, but may be a new, unnamed species. Many reference sources on the web describe it as L. lineata, but its inclusion in that species has not been validly determined. Efforts to induce the plant to form a sporophyte have failed, which may indicate status as a new species. This plant was first mis- identified as Pellia endiviifolia, then as Monosolenium tenerum, before the analysis that determined its true status.
The name means "freshwater seaweed" in German.
Reproduction is by fragmentation. Pieces that break off develop into new plants."
As mentioned above, it used to be regarded as a variety of liverwort, Monosolenium tenerum, which is actually terrestrial, and has been likened to a 'living fossil' because it is extremely primitive as far as plants go. Monosolenium is native to South East Asia and apparently quite rare in the wild:
"In Japan the incidence of this species has declined in the countryside in recent decades—after adoption of modern plumbing. When the old-fashioned privy was current, Monosolenium was a common "weed," as, e.g., around the privies in the periphery of the Mossy Temple at Kyoto...and in settled areas. The plant apparently hardly occurs "wild" and always seems associated with man—much like that other east Asiatic monotype, Ginkgo biloba. It is of interest that this plant, "lost" for decades, appeared on fertilized soil in a greenhouse in Munich, giving Goebel the opportunity to carefully investigate the taxon."
Here's a pic of it:
Think about that, next time you find slime in your privy. You could have a rare plant on your hands! :D
