With assistance from the incomparable Byron, I was able to ID 5 of 6 Mystery plans from this previous post: http://www.tropicalfishkeeping.com/a...-plants-90236/
I studied up, determined a course of care for each, and rescaped the aquarium accordingly. I offer this post first and foremost as a way to thank Byron and to show that the time he spent helping me was not spent in vain. I also have new pics of the Persisting Mystery Plant along with a Brand New Mystery Plant, both submitted for identification assistance. Hence, Help a Fool Redux.
First, the rescape:
I moved the Bacopa to an area where it figures to collect more light. I uncovered the Java Fern and attached it to a rock with rhizome nice and exposed. I also added two floating plants (more on this later). I purchased a bottle of Flourish Comprehensive, which I intend to dose at about 2/3 the recommended volume on the day following my weekly WC. I have also been much more thoughtful and diligent about light duration.
Most of the plants seem to be doing very well. As Byron predicted, I've already begun to see the difference between immersed and submersed leaves on the Echinodorus. I plan to remove the browning immersed leaves in favor of the strong new growth.
I'm doing my best to keep the Crimson Ivy happy. There's some new growth, but at least an equal amount of die off on older leaves.
Here's the Java Fern with a little company in its new setting:
Finally, I submit two mysteries. Up first, this was purchased as a bundle of several stems bound by a metal cuff. It quickly grew very tall but fairly sparse. Here is the picture I originally submitted about a month ago:
Since then, the large stems failed badly. Steady die off of the leaves and very quick rotting of the planted stems. I took a few cuttings of the new growth at the denser tops and replanted them together, but I'm worried they'll suffer the same fate as the mother plant. I'm hoping that I can ID this plant and determine a better course of care. Here's a top view of the planted cuttings (Note: This plant is also visible from a slightly different angle on the left hand side of the Crimson Ivy picture above):
Here's a closeup:
Last but not least, after reading several of Byron's articles and posts, I felt it was important to add some floating plants immediately. I struck out on finding a local source for Water Sprite. While visiting a LFS, I noticed a tank with a very attractive combination of Hornwort and a second plant I did not recognize. The store employee couldn't identify the plant either, but he was willing to part with the entire floating array for $1.50. Although I had told myself (and others) I would never again impulse buy a Mystery Plant, I buckled. Unable to identify this on my own, I submit it for assistance here (NOTE: The Mystery Plant is still somewhat intertwined with the Hornwort, so that there is no confusion about the finer needlelike leaves throughout the background of this image):
Thanks to the forum as always for your consideration and assistance. And if I've not already thoroughly browned my nose, a parting thank you in advance to Byron, as my experience suggests he'll be among the first to lend a hand!
