Lemon tetras are a lovely freshwater fish that can add a special pinch of color to any aquarium. They’re also quite active and easy to care for. But for whatever reason, this species is often underrated in the fishkeeping community. We can’t figure it out, because not only do we love them, we know a bunch of other owners who do as well.
Lemon tetras are native to South America and inhabit parts of the Amazon River. Most often, they can be found dwelling in narrow streams around the Tapajós River basin in Brazil. A peaceful and hardy fish, the lemon tetra is one of the easier freshwater species to care for. These fish make great additions to community tanks and can thrive in large groups.
The appearance of the lemon tetra is both familiar and distinct! They have a similar diamond-shaped body like many other types of tetra species. However, lemons tend to be deeper-bodied and more laterally compressed. Most of the body is semi-transparent. In most specimens, the scales have a pearlescent finish that shines in the light. The caudal fin is transparent and glass-like. Upon closer inspection, you might see a fine black line around the perimeter of the fin that offers more definition. A similar appearance is found on the pectoral fins.
The average lemon tetra size is somewhere between four and eight years when healthy. While there are plenty of instances when these fish have outlived their expected lifespan, it’s usually a mix of good care and luck. Like any other fish species, the lemon tetra’s lifespan can suffer dramatically without proper care. In a poorly maintained habitat, these fish can experience stress, disease, and early death.
The typical size of a lemon tetra is around two inches in length when fully grown. These fish are quite small, making them convenient no matter how much room you have for them.
Lemon tetra care is something that we can wholeheartedly recommend to beginners. If you’re looking for a fish species that thrive in captivity, look no further. These gorgeous creatures are hardy and can adapt to a relatively wide range of conditions.
