Do they need a heater in the tank?


Water temp should be 78-80 degrees F. Anything less and they are
lethargic. So if you can't make the room they are in that warm then yes,
you need a heater. What size tank are yours in? A 25 watt heater is used
by some in a 2 gal size tank. In smaller tanks there is a new small heater
here you could check out:
