It’s been an exciting few days at Birch Aquarium at Scripps. Our baby wolf-eels are hatching!
Our aquarists have so far collected about 250 wolf-eels from the mass of eggs, with another few hundred expected to hatch over the next two weeks. The tiny fish are born brownish-pink, about 1 1/2 inches in length. They begin to turn dark gray within a day or so, and begin snacking on tiny shrimp after a few days. They will grow to several feet in length.
