I won't be getting my new plants until next Friday.. I'm always impatient with these things.
I pulled out the HC and found why it likely wasn't a success... looks like there was some salt particles still attached to the roots and settled under it in the substrate.. I didn't rinse it enough clearly... At least I think it was salt. Hopefully, the Glossostigma will do better.
The snails are already gorging themselves on the algae that has developed throughout the time the tank was cycling. And Notch, my beta is settling in.
