I cleaned out the betta tank today and noticed a bit of growth in the crypt plants that goldfish7 sent me a while ago. Of the 3 plants, one had melted entirely and I threw it away. The other two I left in the tank because I had heard that they often recover from the trauma of melting. So one plant, which had retained one leaf, now has a new leaf coming, and some new roots growing. The second one, which had melted to a nub with a few roots, now has some green appearing on the nub, and more roots! I'm very glad that the plants are recovering.
I look forward to them growing out. From the pictures Goldfish7 sent, they are really unusual - kind of bright green with bronze stems and veins.
I haven't had much luck with plants in the betta tank, so it's nice to see something happening.
