The milk spotted puffer, also known as the milk puffer or South American puffer, is a freshwater pufferfish found in South America, specifically in the Amazon River basin. It can grow up to 8 cm (3.1 in) in length and has a distinctive spotted pattern on its body, with a creamy white base color and small black spots covering its body and fins.
Milk spotted puffers are known for their aggressive behavior and should not be kept with other fish, as they can attack and injure or kill their tank mates. They are also known to be sensitive to water conditions and require a well-established and cycled aquarium with high water quality. In terms of diet, milk spotted puffers are carnivorous and require a varied diet consisting of small live or frozen foods such as bloodworms, brine shrimp, and small pieces of shrimp or fish.
