I suspect that coldwater coraline algae can't survive our tropical temperature tanks, but I figured I'd ask in case somebody has tried with any success. I'm out dragging scallops on the coast of Maine, and every haul brings up the most beautiful purple coraline covered rocks. There's a 40 degree temperature difference between north Atlantic water and tank temperature, but this stuff seems to grow pretty aggressively. A handful of benthic fish had it growing on them. I figure any souvenirs I wanted to put into my tank wouldn't survive even a slow acclimation, but I thought there might be some chance for corraline. Has anyone tried it or otherwise knows definitively?
