Revered for their vibrant colors and eye-catching shimmer, the Congo Tetra (Phenacogrammus interruptus) has become a widely popular freshwater fish species in the aquarium community. They were first discovered in 1949. However, due to breeding difficulties, it wasn’t until the 1970s that these fish became a staple in tanks across the world.
As their name would suggest, these fish are endemic to the Congo River basin. They typically call small streams, ponds, and marshes in the area home.
They’re a schooling fish and typically stick to large groups in the wild. In captivity, this schooling nature creates stunning swaths of color that will be the center of attention in your tank.
