Heating Plastic Tanks

[AngelOfDeath]

Can you put a water heater in a plastic tank, the tank is 4.5 gallon. I am curious becuase i want to buy a heater for my betta as the temp does not always remain consitent

Would there be any complications if i were to put a fish tank heater in a PLASTIC tank

thanks!

Hi
I've been told that the heater will eventually make the plastic very brittle making it prone to breaking. I do believe there are some acrylic tanks that can cope with a smal heater with a heater guard on, but the warmth of the water may still render the plastic brittle.

Cheers

I used a 50w heater on a 2.5g/ 10l acrylic, no probs 50w is for up to 50l tanks.
