The red color is very striking and the fish is active and curious. I’ve had it for six months and it’s grown to about 5 inches. It’s not the quietest fish, but it’s a great centerpiece in my 120-gallon tank.
Phil Hudson –
Beautiful fish with vivid red fins. It’s a bit aggressive toward smaller fish, so I removed a neon tetra after a few weeks. Still, it’s a great addition to my setup.
