Default Oscar without Heater?

Does anyone have experience keeping an Oscar without a heater?

I have some local fish in two tanks (50g and 125g) and the water is room
temperature (around 64). I was wondering if an Oscar could live in such a
tank.

Not without developing the urge to grow arms so it can grab you by the
front of the shirt and demand to know why $40 for a couple of heaters is
too much to ask.

No they cannot. Oscars are TROPICAL fish NOT coldwater fish. That
would be like putting you in the Artic without a coat. Break down with
yourself and buy a heater! The water should be anywhere from 75 F to
82 F.

Not according to this report from the Florida Museum of Natural
History.

"Dispersal northward in Florida appears to be restricted by
temperature. A 1982 Florida Game and Freshwater Fish Commission study
determined the lower lethal temperature for this species is 12.9 C.
In its native range, the oscar is valued by artisanal fishers as a
food fish."

Thats approx. 55F.

I don't have heaters on in my tanks at night, although they are on all
the time the lights are on, containing angels, red eye tetras, rummy
nose tetras, plecs., and harlyquins, they all do fine and even the
plants, all crypts., grow like mad. The temp in the tanks can drop to
68F, the lowest I have recorded is 64F but that was a very cold
night and I hadn't left the central heating on to compensate, the
heaters when the lights are on maintain the tanks at 78-80F. When
doing water changes I remove 20% approx. and replace it using the
garden hose direct to the cold water tap adding de-chlorinator. I live
in Scotland so it isn't as if the temperatures are tropical

It works for me, and has done for years, but I wouldn't recomend a
newcomer to do it, you have to watch the temp in the tanks doesn't
drop too low too quickly, especially in winter, I sometimes have to
stop and wait a while before filling all the way.

I clicked on the above link and couldn't believe what I read -- I'm
starting a new thread. The Florida Museum must have posted this web

From some of the posts on here and resources left the native Oscar likes warm water but leathal temperatures are around 55 degrees Fahrenheit.
I also have a tank with local fish in it such as bull head cat, pumpkin seed sunfish a couple brookies and a few large shiners, and a few tropical, an Oscar be one of them. My tank reaches temps of almost 80 in the summer and not above 64 in the winter. Mostly because it’s kept in my garage

Well, I appreciate the response; however, I would point out to both you and
Polarhound that buying a heater is *not* the issue. As I pointed out (I
thought quite clearly), I have fish that do not want to live at 82F and I'm
hardly about to kill them off so that I can buy an Oscar. I was just curious
if an Oscar could survive in the tank I have. I guess not.

Thanks.

Jonathan

It doesn't need to be at 82F. Oscars can be happy in the mid 70's. The
ideal temp range for Oscars is 73-82.

Keeping Oscars at 64 will get you a lethargic unhappy fish. As well,
what happens if your heat goes out during the colder months? Even in
the south the temps can get down to frost-forming levels.
