I used the hornwort to take up excess nutrients while setting up a new planted tank. The plants are now established and I don't need the hornwort anymore. Fast growing, normally floats, but will throw down thin roots. Provides cover for fry and shrimp. 99% certain it will contain snails, snail eggs, and possibly rainbow fish eggs. The photo shows the 40 long tank it'll come from. I'll give you all of it.
