That will be why they look out of place then lol.Thank you Sk3lly!
The black ones are only there to keep the driftwood down
Will remove them in some weeks..
Thank you Andrew,
the roots are growing out of the Wabi Kusa when placed in the tank. In emersed state they grow more or less inside the Wabi Kusa.
At the Moment they look quite intact as far as I can tell... the plants are covering it completely.
Can I ask exactly what hydrocotyle that is? The growth is really compact!
