This is not the classic goldfish! and we are not in a glass bowl! What we see in this video is the Apogon imberbis, the Cardinalfish, filmed in one of the many caves that characterize the rocky shores of the Mediterranean Sea.

This fish of the Apogonidae family is a rather widespread species throughout the Mediterranean Sea, it lives in the darkest and most inaccessible caves and ravines, for this reason it is difficult to see it snorkeling from the surface.
However, it is a beautiful species to photograph and film if you can approach it in its cave, without making too much noise and scaring it. Like most fish, if left alone, it will come closer to see and study the underwater intruder.
The curiosity of this species is that in summer it is often rather shy and cautious. The reason is that males keep the eggs laid by females in their mouth waiting for hatching, so it is practically impossible to get close.
In our case, two Cardinal Fishes approached and as seen in the video instead of running away, for a few moments the two specimens let themselves be filmed just enough.
