An exciting new longfin clownfish for those who appreciate unique and rare fish. There are a few longfins being produced these days but in our opinion Sea and Reef produces the nicest! Why do we say that? Typically longfin clownfish have jagged and uneven fins that are stiff. Sea and Reef however, thru a different strain of genetics, has developed a more even and soft flowing longfin. The length of the fin develops as the fish ages and matures which typically happens with 8-12 months of age. Being a Domino, this fish will also turn jet black as it matures just like the regular Domino. This usually happens when they reach an age of around 10 months or so.
