Just had some cuttle fish hatch the other day and they are finally able to do their colour change bit. They are all practising colour changes; it appears they couldn’t do it till two days old. I tried to get them to fade in and out but until today, they couldn’t do it. Now they’re acting like a kid with a new toy, they appear to be all playing with their new capacity. This little one was the winner’ it was like a light flashing off and on. In fact at one stage they all looked like stars blinking in the sky.
