Elizabeth James –
I’ve kept the Pearly Jawfish for six months in a 30-gallon tank. It’s very calm and doesn’t bother the corals. The fish is active during the day and hides in crevices at night. Easy to spot and maintain. Great addition to a reef setup.
Lauren Howard –
The fish has adapted well to our tank. It’s peaceful and doesn’t chase other fish. We noticed it’s more active in the morning. Tank size is sufficient, and water parameters stayed stable.
Mary Dowd –
Perfect for intermediate reef keepers. It’s not aggressive and blends well with the environment. We’ve seen it feeding on small crustaceans near the substrate. Very satisfied with the purchase.
