25watt Heater Suitable For A 2.5ish Gallon?

[Neon.Tetra]

Is a 25watt suitable for a 2.5 Uk Gallon tank?

Across the internet it seems to be debatable. Some people have said the tank would be fine without a heater at all, others have said it would be ok on a lower setting? Thought I'd ask you lot here.

It will be fine. Is the tank acrylic or glass? If it is acrylic, make sure you have the heater held away from the sides.

The tank is quite light, so it must be acrylic. How will I keep it away from the sides?

You can use those suction cups and put it on the sides.
