I just came back to this thread to add that the Theo heater makes a very slight "click" noise as it switches on and off. It doesn't bother my betta at all, but then he's a pretty fearless fish....a shy betta might get startled or it might just annoy you when you're trying to sleep. ;)

). You simply add a small amount with every water change to feed the plants.
That's great advice! Thank you. I ordered some java fern, water sprite & java moss and now I'll have to order some of that flourish, since each of my tanks house a single fish.
