Okay so I was pretty sure my heater was working, come back home today and find out the tank is at about 19 degrees c... Heater is set for 30. Yikes. I have a betta, anyone from the UK know a good heater? I need about 50w-100w, I have a 12 gal (55L) tank. I'd really prefer one that isn't made of glass since I'm extremely anxious about it cracking or something. I know it's unlikely but I deal with horrible anxiety haha. Is there any way I could keep him warm for now? I wanted to do a warm water change but I don't wanna put him through temp shock. He seems somewhat okay tho. He eats and comes up to greet me a lot. I can order the heater today, I just need to know some good UK ones, and preferably non glass.
