I have a 5 gallon aquarium and would like to add a 50 watt heater for the winter, as temperatures are already starting to drop. However, I already have my three fish in it. Is it safe to add a heater while fish are in the aquarium, and does anybody have any tips on how I might go about it??

Thank you!
Sorry! They’re danios. Definitely tropical fish.

I just moved to a new apartment and we have a gas heater. It is a square gray thing in the wall with a pipe attached to it. How does this heater work? Does it circulate through the walls and warm all the rooms? It doesn’t seem to because when we close doors the rooms get cold?

Also, how expensive does it get? We have been keeping rooms closed that we don’t use during the day to conserve heat but do we really need to do that?

Would love to hear from folks that have either water heater. Please tell me about it’s performance, how long you have had it, has it needed repairs, are you happy with the unit and any other helpful information.
