Could a reptile heater be used to heat water? I was thinking, since heat rises, to put a reptile heat pad on our counter (marble) and set the fish on it. Maybe it would be too hot.
I tried a heating pad and it seemed to work really well. (Was an emergency as the water was at 70*) Little Velvet (his name) has buried himself at the bottom sometimes and they seem to be more active.
Lamps on them? How?
Otherwise, how could you heat these? We have two 1/2 gal and one 1 gal. I know I need to put them in larger spaces but not sure where to put them then. We also have 6 giant Hermit crabs in a 60 gal tank so.....space is tight. I have an empty 10 gal tank but then only one fish would get to move up in the world.
