What are some low light plants?

Yes because it is a Cryptocoryne.

 

I take it that's what they do then lol.

 

Yes they do when they are in the open and under good lighting.

 

It would be much easier to tie the moss down to the rock with a fishing line.

 

Or cotton sewing thread.

 

Hmmm. I didn't think I had adequate lighting (1t-8 bulb over a 26 gallon bow front), but I supposes I do (I figured it would be stretching for the light if it wasn't, so I was a bit unsure). I still have a 6500K bulb coming this week anyways.

 

Thanks for the pointers on that.

 

That should be in the low light range unless your reflector is highly polished.

 

No, I don't think it is. It's a pretty old fixture that came with the tank (Pet's Mart like combo) years ago. Cryptocoryne must be a really low light demanding plant.....and since we're on the subject, would CO2 injection be better than a liquid form of carbon?

 

That would depend on the plants. Mosses can not handle liquid carbon well. So CO2 would be better. But it is not needed in low light tanks.
