Bella Poole –
The soapfish is very active and shows great coloration. It’s been two months in the tank and still very curious. The stripes stand out well against the coral. Easy to feed and doesn’t stress other fish. A great addition to a 100-gallon reef.
Anna Ferguson –
Arrived healthy and active. It’s been patrolling the rockwork since day one. Feeds well on small crustaceans. A bit semi-aggressive with a larger fish, but manageable in a well-established tank.
Claire Hemmings –
Beautiful fish with vibrant black and white stripes. It’s calm during the day and active at night. Very responsive to feeding. I’m happy with the purchase and would recommend it to others with a beginner reef setup.
