Pygmy hatchetfish

The Pygmy hatchetfish is a small, freshwater fish known for its silver body adorned with subtle hints of green and blue. Originally from South America, it possesses a unique, hatchet-shaped profile due to its deep, laterally compressed body which aids in its distinctive way of swimming. Despite its captivating appearance and peaceful nature, the Pygmy hatchetfish is not as widely recognized or prevalent in the aquarium hobby compared to other more popular species. Though it may not be well known among casual hobbyists, its unique characteristics make it a prized addition for enthusiasts seeking to diversify their aquatic collections.
