The First Designer Basslet? Meet Biota’s “Platinum” Gramma dejongi

Named the Platinum Dejongi, captive-breeding has produced a variant of this rare species where the normally magenta markings on the fins are replaced with near-white coloration.

After their debut at MACNA 2019, the first-ever white variants of Biota’s Dejongi Basslet are now being formally introduced to the aquarium trade. After patiently awaiting to ensure the unique coloration wasn’t a fluke, a consistently low-level occurrence of white-finned Gramma dejongi in Biota’s captive-bred offspring has allowed their introduction into the aquarium hobby.

The Cuban or Dejongi Basslet (Gramma dejongi) is already one of the rarest fish in the country, but the Platinum Dejongi, adorned with a bright white coloration instead of the deep purple we’re accustomed to seeing, is now available. These individuals are also among the largest Dejongi that Biota currently has available; most are over 3 inches long!

    On the Dejongi basslet what size tank and reef would be preferred?

      Given their similarity to the ubiquitous Royal Gramma relative (Gramma loreto) I think their care requirements are probably a mirror image of the sibling species. Depending on who you ask, while some folks might say a 10 gallon is fine for a single fish, most references put the minimum for a single in the range of 20-30 gallons.
