Hornwort plant

When I received my order that I made on May 22nd 2020 my order was hornworth stem plants which had no roots but that didn't bother me too much because my pH was about 6.5 because I had neon tetras and I have root tabs and fertilizer and iron supplements and I thought they would root but they died

Great packaging

I needed something for my fish to hide in as I have some larger, more aggressive fish. These came packaged in an insulated bag with a gel ice pack. I will not be ordering more until the fall, as I live in Texas and I do not think even these will work while sitting in my hot mail box. It's been a couple of weeks now, and the new growth just started showing up this week, Healthy plants!

Beautiful, beautiful!

This Hornwort is growing like that's its job! I did try initially to make it grow in the bottom gravel like a conventional land plant, but it grows full and lushy all across the top of my tank like a green cloud. This suits my koi babies (bottom feeders) to a T. I am quite pleased.
