Anubias 'Petite' well grows in emmersed culture.

It is photo from my collection. I use the burnt clay as a substrate.



The same plant in Moscow Botanical Garden looks so:



Leaves in the last case are higher and longer than in my collection. It can be connected with use of more nutritious earth as a substrate, as well as with lower humidity in greenhouse.

Slivun: Do you keep your emmersed anubias in a terrarium or other enclosure to keep the humidity high?

I flooded the set-up on Friday morning, so these have now been underwater for 3 days. The leaves look like they are beginning to die (leaf tissue turning dark). Is this normal going emmersed to submersed (I didnt' notice any real change going from submersed to emmersed)? These past 3 days I also have not fertilized, another possibility.

Any experience or suggestions welcome and appreciated.

Some melt/death is common. Macrophyte cuticles thin out during submersion; the thicker submerged cuticle leads to oxygen exchange issues, and the leaf essentially suffocates. Definitely keep up on the ferts; the last thing you need right now is limiting nutrients.

Thanks Philosophos. The ferts situation is now taken care of.

On a side note, I just went on a field trip and came back with 3 banded pygmy sunfish for this tank. I'll post pics later in the Biotopes forum (East Texas Wetlands thread).

Yes. All anubiases I keep in small greenhouses (less than 1000 litres):
