Hi,
I noticed several larger Chromis chromis gojng round in circles on shallow rocky bottoms, surrounded by smaller individuals two weeks ago (25 June). What behaviour is this please?

These are probably the behaviours that precede reproduction, see here.
Il s'agit probablement de comportements précédant la reproduction (+ lien).
