Gentoo penguins

Not a holiday in Antarctica (unfortunately), just a trip to Melbourne Aquarium.
My sister and her children are visiting from New Zealand, so my children had time off school (it was educational...) to visit the Aquarium, which we haven't been to for many years. I always find videoing in an aquarium comes out great, but still photography is never very successful - it's too dark and the fish are too fast, the perspex has too many reflections etc. So this is pretty grainy.
I wonder if I can manage one blip a month?
