One book suggests a relation of these fish to Piranhas, we are not sure about that, this is salty ocean water, not the Amazon river. But these fish do behave like Piranhas: We fed them a few pieces of bread, chips, chocolate, meets, and once they figured it out, swarms of these fish were fighting for a bite, sometimes moving on top of each other, out of the water.
"Prolific is the word which comes to mind. A member of the Trigger family, it is found in most tropical waters, but nowhere is it so overwhelming as off Ascension. The many colours of the blackfish are brought out by flash light. It is a scavenger and will eat most things. At night they sleep on their sides on the seabed."
Dirk did hang a foot in the water, which was inspected closely, but had no takers. What would happed when you put a piece of bread between the toes?
Besides, the water is too cold for a swim, to us.
We spent the day playing with fish, some maintenance on the boat, and watching the RMS St Helena being unloaded.
