yes to chilis, yes to ruby tetras (i need to check on them, they are still in qt but looked good before I left). I don't know to subwassertang- it had some hair algae in it so you may not want it. I will look through the tanks and see if I have any in good shape.
As you can see, I am back home. Today will be spent catching up on emails and doing 80hundredy milliondy water changes. Hope to be back to speed by tomorrow.
