Mia asked:


I have a heater for my acrylic tank and the surface doesn’t get hot. So, can I use one in my plastic tank?
Or do I need to add a heater? I have never had fish in the cold weather. My fish for my own personal tank have heaters to be ready for the winter months, but this is for a teen who has a fish for the first time. So, will the water actually get very cold if it is kept away from drafts?

I have a 12 gallon nano tank. The heater popped out of the glass encasement and made bubbling noises. I unplugged and removed it but there seems to be a black chemical in the tube of the heater. Also my anemone and all my coral shrunk and all my fish are in shock. Is it a chemical problem and do I need to replace the live rock and live sand?

I have a 10 Gallon aquarium and the heater just recently stopped working. I purchased a heater (Guardian) that says it is good for a 30 gallon tank, and I want to be sure that the heater isn’t going to heat my tank to much.
