I ended up getting the double so I could add a second if I needed the temp higher - probably wont be the case.
They do have an led one as well. Shoulda got that one I guess... oh well, I might be selling a submersible halogen for cheap soon.
Dude, I've read about barnacle gobies but have never seen one. Speaking of mythical beasts, did those sexy shrimp come in yet?
