So I have 2 bettas in 2 gallon plastic tanks. They both have thermometers that say it's above 75 degrees, and I changed the water about 4 days ago. (will change again tomorrow)
I bought 2 heaters that can go under the gravel. they are a 2-5 gallon heater
I want to put a heater in. but it's a plastic tank, so I'm afraid to.
What if I put a ton of gravel on the bottom, then the heater, then more gravel on top of it?
Do you think that will prevent the plastic from melting? I'm really scared to put it in.
I am getting 2 new betas, who will have glass tanks. (too complicated to explain)
I will upgrade these 2 to glass tanks soon, but not that soon.
