Venom SS;2702111; said:There are many bodies of water in Texas that get well over 85 degrees for months at a time, and only dip below 70 degrees for 2-3 months out of the year. Gar are probably one of the most common fish here. Being that ive observed them for over 20 years, I find it hard to swallow that Gar wont thrive at high temps.
it really turns into an argument of semantics...thriving vs surviving...if one thinks about it, fish survive where they can...in the wild, this is often regardless of where they really prefer to be. in cooler temps they won't have to surface for air as often as the water may hold enough O2 for their activity level or they may be at a more optimum metabolism. at warmer temps they definitely have to surface more often (kind of like "working harder") to maintain activity, foraging, etc.
another issue is comparing wild conditions to captive conditions...captive conditions should try to keep the best interests of the animal in mind...there is no need to keep a gar at extreme heat or extreme cold in captivity...something around 65-80F works well, with warmer temps helping to stave off some parasites and infection, and cooler temps helping to regulate activity and metabolism a bit better.
we've all seen gars in extreme conditions (think of the Audubon Aquarium and their gator gar in the big saltwater tank; that gar survives, but is likely not terribly "happy" due to extra energy needed to compensate for differences in osmotic conditions), that doesn't mean they should be kept in those conditions in captivity.--
