I read the thread as well. He was asking about different growth rates and seemed interested in knowing why the rays weren't growing out at the same pace. He was running the temp high to grow them out is what I got out of the posts.I think you may have misunderstood me...the guy was running his ray tank in the high 80's as a normal constant temp. There is solid evidence that this will drastically shorten the life of a ray. I run temps at 80-82 for pups to get them gaining weight fast, also like to run a higher temp for newly aquired WC rays to get them eating and stable. Larger established rays mid to upper 70's is where I'm comfortable keeping the temps. So you think I'm wrong, yet you follow the same method? Confusing
Running High temps is like running at the red line on your tachometer. You can do it for short periods and not hurt anything, but constantly using it is going to mess stuff up.
