Dude, if these fish can survive winters in places like Michigan, Ohio, Maryland and what not then I'm sure they could survive a westcoast California winter.
I mean you're by Laguna Beach, LA,San Diego. I don't think many pools freeze over around there. :cool:

gar are illegal in cali. ur askin for trouble doin it. and while certain gar species can survive low temps, certain regional gar can survive colder. A spotted gar from michigan can survive colder temps than say a spotted gar from luisianna

not necessarily...the max tolerances of both of those populations seems to be about the same...i just ran an experiment looking at those exact sorts of differences in temperature levels. both populations are best acclimatized to hotter or colder temps in captivity, not just tossed into them. if the change is gradual, they'll both perform the same...if it is drastic, then it would shock both about the same as well.

on a species level you'll likely see more of an issue with temperature tolerance...although tropical gars can survive in less than tropical temps, they would likely struggle overwintering like longnose/spotted/shortnose can.--

Mexican Population Trops minimum out at around 60 and still continue to feed although at a very reduced rate. At 50 they go into a topor and pretty much just about get ready to die. Never tried testing changes in temp with the Cubans. But then why? Their environment averages pretty much even year round plus or minus 10 degrees. Mature Gators will go down to 45 without much problem. Juvenile Longnosed, Spotted and Shorts can take 40 (Never tried lower) for short periods. average is better around 50 for a cool down period. Florida I have dropped to 55 and regularly do so but have not gone further. There is actually a benefit to keeping the Temperate gar species in temperate conditions. This is little practiced in the hobby but is worthy of exploring to those that can do so.

But anyhow temp acclimatization is absolutely required for any of these fish. Abrupt or quick changes in temp will quickly weaken the fish if not kill it.
 
i have spotted and alligator. the thermometer says 30' celsius. is this okay? i live in the philippines and its getting hot here.

I did the math and 30c = 86f

That's pretty damn warm, but I am not sure how dangerous that is. I mean allot of people who use aquarium heaters set them around 80 degrees and 86 is only 6 more degrees higher, but it's pretty close to 90 which doesn't sound "Gar Friendly" to me.
Just my 2 cents, I'd wait for some others to chime in like Sol, or Perun.

My gator gars are most active and have a voracious appetite at 30C, so yours should be ok.

the top temps of our temperature trial experiments were 30C (sometimes a bit more); although they can survive at these temps, they were not optimal for growth. when they need to expend a lot of energy to put up with the heat, they don't grow as efficiently (plus those temps are just generally unnatural).

we found with spotted gars they grew most optimally around 74F, gators shouldn't be far off from that. one would expect tropical and Cuban gars to have a bit higher optimum.--

Does the temp for the spotted gar include floridas too? Or just spotted?

the experiments i was referring to were only done on spotteds, so they would be comparable to Florida gars, but not exactly the same. FL gars in the wild definitely experience a warmer temperature for longer periods of time out of the year, but their tolerances are likely similar (this past winter was no doubt a test for them in the wild) --
