Even the fish sometimes get pissed off
Parrotfishes Pesci Pappagallo Scaridi intotheblue.it
During a dive in the coral reef of the Red Sea I met two Rusty Parrotfish who were fighting each other in a really aggressive way, as you can see from the video. They will have had their good reasons. Generally we have noticed a good cohabitation between fish of the same species and I don’t remember to have witnessed a similar scene. Surely they fought to defend the territory, in fact we know that during the mating period the fish create their own Harem and do everything to defend it. In fact, you can see that one of the Parrot fishes eventually has to give up and is forced to leave.
Parrotfishes are a group of about 95 fish species regarded as a family (Scaridae), or a subfamily (Scarinae) of the wrasses. With about 95 species, this group displays its largest species richness in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion.
Parrotfish are named for their dentition, which is distinct from other fish, including other labrids. Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates (which contributes to the process of bioerosion).
Maximum sizes vary within the family, with the majority of species reaching 30–50 cm (12–20 in) in length. However, a few species reach lengths in excess of 1 m (3 ft 3 in), and the green humphead parrotfish can reach up to 1.3 m (4 ft 3 in). The smallest species is the bluelip parrotfish (Cryptotomus roseus), which has a maximum size of 13 cm (5.1 in).
