I made a mistake with the identification of my fish. They are actually Three-spined Sticklebacks and not Mackerel fry. A member of the irishfishkeepers.com forum pointed my in the right direction. Thanks Bullfrog.
They only grow to 4-6cm so I might be able to hold on to them which is the good part.
They seem very happy now and not so shy anymore as they are also coming to the front glass even when I am at the Aquarium. Great to watch how they school. The inevitable happened and one ended up as a snack. Actually two Snakelocks shared it 😉 although I think the bigger one won in the end.

Hi Marius, what beautiful little fish! I have not seen them yet here; they would make a great addition to my aquarium….cheers, Michiel
Hi Michiel, They are amazing to watch, I was extremely lucky to find them trapped in a big pool with a channel to one side where i could kind of herd them in. Otherwise it would have been almost impossible to catch them. So fast! Hope you will find some too one day on your rockpool hunt 😉
