We set the limit temp swing at 8 to accomidate and limit the stress level on a variety of animals. But that depends on what species we are comparing and who is talking.
I disagreed with the statement that said we did not need heating and chilling technology, because it was just plain dumb. You cant say that cold-water species such as the Catalina goby or the blue spotted jawfish would do just as well with temp swings of 20 degrees. <span style="color: Red">I think you read more into his statement than what I did . I think he was referencing the method of sale of this equipment by some stating a 2 degree temp swing is detrimental </span> Also, i don't believe all species are able to cope with that kind of stress on a daily basis. Maybe this artilce would have been true if it presented a specific biotype and compared it to an aquarium biotype but it did not. It was incomplete science in my opinion.<span style="color: Red"> Much like our anecdotal evidence presented by most in the hobby.

you correct in
assuming<span style="color: Red">( </span><span style="color: Red">not an assumption)</span>many species overlap however there are many endimic species in the ocean, ones that can handle and need extremes and others that do not. Species that live in tide pools will be different than those that live in deep water. Not to mention many species just live in certain parts of the world. (ex. the lion fish, until recently) perhaps the ones that are able to spread into other biotypes are hardier as well? I dont know enough to prove that,
and the author didn't convince me of much.<span style="color: Red"> I don't think that was his intent</span>.
