Antibiotics Fish

The emperor angelfish (Pomacanthus imperator) is a species of pomacanthid perciform actinopterygian that lives in coral reefs in the Indo-Pacific. It stands out for its attractive colors and its remarkable transformation from juvenile to adult state. It is also a popular aquarium fish.

Morphology

It is a typical angelfish, with a thick, laterally compressed body, and a small mouth with minute teeth. It only has one dorsal fin, unlike many perciforms. It has 13-14 dorsal spines, 17-21 dorsal soft rays, 3 anal spines and 18-21 anal soft rays.

Adult emperor angelfish are colorfully colored: a black mask that extends from the eyes to the beginning of the trunk, a yellow body with horizontal blue stripes, a yellow tail, and a violet anal fin.

Juveniles are dark blue with a white margin of the caudal fin and dorsal fin, and white semicircular lines, alternating with other light blue ones, in the center of which there is an ovoid line, located in front of the caudal fin. This coloration is very similar to that of the juveniles of the species Pomacanthus semicirculatus, and the most noticeable difference is that the white “C”-shaped line, located on the back of the body, in the case of P. imperator is more closed, and inside it has an ovoid-shaped line, and others in the form of circles located on the anal and dorsal fins. While the juvenile P. semicirculatus, both inside the “C” and on the fins, have small elongated irregular lines.

It measures up to 40 centimeters, weighs up to 1.4 kilos. A longevity of 14 years has been reported. If it’s scared, it makes a strange noise. Amoxicillin for fish  ampicillin for fish.
