Puffer Dogface 
The Arothron Dog-Face Puffer often referred to as The Blackspotted Puffer, gets its name because of its resemblance to dogs. Its appearance changes during various phases of its life. When it is in its gray stage, it appears gray, with black markings on the mouth, eyes, and dorsal fin. The pectoral fins are an appearance that is yellow. The half-yellow stage is identified by the yellow underbelly and the overcoat of dark gray, and the face appears like the gray one. There may be spots of black on the body and could be yellow or gray. It rarely alters its color within an aquarium. The Arothron Dog Face Puffer does not have pelvic fins, however, it is extremely maneuverable due to its dorsal, pectoral, and anterior fins. It is not "teeth," it has an elongated beak-like structure that can be used to crush prey. A 100 gallon or more carnivore aquarium that is exclusively fish-based is ideal. Arothron Dog Face Puffer is an excellent tank addition because of its personality and distinctive appearance. It is able to eat invertebrates inside a reef tank. It is tolerant of other Puffers that aren't more aggressive than it is. It's timid at first, but then gets scared when placed in a net. Therefore, utilize a container for transferring it. The Arothron Dog Face Puffer requires a variety of meaty meals, such as shrimp, krill, squid, and hard-shelled shrimp, to reduce the size of their expanding teeth.
