in my glass tanks i have heaters but don't know what to use in my plastics tanks, are there certain heaters for plastic tanks or can you just use normal heaters
I have quite a large heater, its only an 8gal tank but the 25w heater that came with it was broken and when i took it back to the store all they could offer me was a 100w heater which keeps the water at a constant 30 deg (on its lowest setting)
My betta seems to love it though, so i guess its okay. They like slightly warmer water anyway dont they.
