Sexlineatus Grouper
The black and yellow lined soapfish, also known as the Barred Soapfish or Yellow Emperor Snapper, requires a large, well-established aquarium with plenty of hiding places. These fish are generally yellow with black stripes, including one through the eye and another mid-body stripe. They are known to consume any fish or invertebrate they can fit in their mouths, but generally avoid corals. They can also release a toxin when stressed or threatened, which can resemble soap.
Aquarium Size
A minimum of 100 gallons is recommended due to their potential size (up to 10 inches).
Aquascaping
Provide ample hiding places like caves, overhangs, and ledges using rocks and driftwood.
Tank Mates
They are generally peaceful but should not be kept with small or slow-moving fish that could be seen as prey.

The fish is active and colorful, with clear black and yellow stripes. I provided plenty of rocks and caves as suggested. It seems peaceful and doesn’t attack other fish. Only noticed the toxin release once when it was startled, but it’s not a frequent issue.

Great addition to a large tank. The fish is very visible and adds a striking look. I made sure to include hiding spots and avoid small fish. It’s not aggressive and has adapted well to the environment.

It’s a beautiful fish, but I had to be careful with tank mates. I removed a small shrimp that it ate. It’s not a threat to corals, but it does eat small invertebrates.
