Are they hard to care for? I only have regular 15w (or something equally low) flourescent on this 10g. I won't be upgrading lighting for a while. They came with the rock and shrooms. I didn't even see them until a month ago. And the only reason I got the shrooms with the rock was because the fish and pistol shrimp I wanted would not leave the rock, even after we took it out of the water. So they gave me the rock and all its inhabitants.
I put the rock they're on at the highest part of the tank. Hopefully they'll be fine for a few months.
