Heater or no heater?

  1. Dlondon95 Well Known Member Member

    I've been doing some reading and I just wanted to know what you guys thought about keeping tanks without heaters. I know a few people do, but what about the rest of you. Would you go without a heater?

    Some people say "Yes, fish NEED a temp of, say, 76F" and other say "no, the science of blah blah blah allows the fish to live in cooler than 74F water because of how they live in the wild blah blah blah"

    The reason I ask is because I have several tanks laying around with filters and everything, but no heater! I want to set them up, but temps in my house can drop pretty low (68 is normal for upstairs and 60-65 for downstairs in the fishroom). I'm not saying I will be setting them up. I like to have a heater just to be on the safe side.

    So what are your thoughts?

    Tropical fish need the heaters IMO ....a fluctuating temp causes stress and we know what that can do to a fish....a few degrees up and down dont matter but here in NH , we were 80s last week and 30s this week...without heaters, I think id have a bunch of ICH fish on my hands ;)

    All of my tanks with the exception of the bettas have heaters. The bettas do nut until I get new bulbs for their lights as the lights heat the water and if I have a heater running the water gets up to like 90+.

    I plan to have all of my tanks with heaters tho.

    EDIT:
    I even have one on my goldie tank but its only set to 72 degrees so it only kicks on when my house is cold. Which generally is in the winter since its right next to a door.

    That's exactly what happened here! The temp in the house didn't change but a few degrees, but outside was just... Wow.

    The only tank I have no heater in is my shrimp tank. They seem to do better for me in lower temperatures.

    Probably depends on your home, most people with a large fishroom just heat the room to save costs instead of each tank individually. If your house is always warm you would probably be fine but if it gets as cold as you say then a heater would be required.

    I kept a 55 gallon tropical community tank with no heater no problem... but the room they were in also housed the pellet stove, so it was never under 74, usually it kept a steady 76, so I think that that was a special circumstance... Normally I would never keep a fish without a heater...

    Good morning,

    :animal0068:I have moved your thread from General Discussion to Freshwater Tank Equipment/Heaters section of the forum.

    I recommend heaters for your tanks. :)

    Thanks Ken.

    I just wanted to see what everyone's opinions were. I, too, think that every tank should have a heater.

    I looked in my tank last week and the temperature was below 70 degrees. One of my fish had ICH. It turned out the heater was broken... probably no more than a day or two or I would have noticed and my fish was sick already!!:;sh

    I think if your house stays at a consistent temperature it would be ok. My house is not only inconsistent, but we drop the heat or air considerably during different times of the day ie at night, when we aren't home etc. Our house can go from 65 to 73+ and back in the course of a day.
