Unique and Unusual Pet Fish Types You’ve Never Heard Of

Fishkeeping is a hobby that has captivated humans for centuries. The tranquility of watching colorful fish glide through the water can be incredibly therapeutic. While most of us are familiar with common aquarium dwellers like goldfish, bettas, and neon tetras, there’s a whole universe of unique and unusual pet fish species waiting to be discovered.

In this article, we’ll take you on a journey through the lesser-known but utterly fascinating world of pet fish. From fish that resemble living gemstones to those with intriguing behaviors, you’ll be amazed at the diversity and beauty that exists beneath the water’s surface.

1. The Electric Blue Acara (Andinoacara pulcher)

Imagine having an electric blue gem swimming in your aquarium. The Electric Blue Acara is a stunning freshwater fish known for its vibrant and almost iridescent blue coloration. Native to South America, these fish are relatively peaceful, making them suitable for community tanks. Their striking appearance and docile nature have made them a sought-after addition to aquariums around the world.

Electric Blue Acaras typically grow to a size of around 6-7 inches (15-18 cm) and prefer well-maintained tanks with plenty of hiding spots. Providing them with a balanced diet and clean water will help them thrive and maintain their vivid blue hue. Keep in mind that they can be sensitive to water parameters, so regular water testing is essential to ensure their health.

2. The Axolotl (Ambystoma mexicanum)

For those who want a truly unique and unusual aquatic pet, the axolotl fits the bill perfectly. Often referred to as the “Mexican walking fish,” axolotls are not fish at all but rather a type of salamander that retains its aquatic larval form throughout its life. What sets them apart is their bizarre appearance, featuring feathery external gills and a perpetual smile on their faces.

Axolotls are native to the ancient waterways of Mexico and have become popular in the aquarium hobby due to their distinctive charm. They come in various colors, including wild-type, leucistic, albino, and melanoid, allowing you to choose the one that appeals to you most.

One fascinating aspect of axolotl care is their ability to regenerate lost body parts. If an axolotl loses a limb, it can regrow it with astonishing precision, making them the subject of scientific research on tissue regeneration. However, to provide them with the best care, you’ll need a spacious tank with cool water, around 60-70°F (15-21°C), and a soft substrate to prevent injury to their delicate skin.
