Those who have been in the hobby long enough know that the Bristletooth Tomini Tang (Ctenochaetus tominiensis) is an often under-appreciated workhorse fish that is excellent for keeping undesirable tank algae in check. For that reason, we were super stoked to see the wickedly odd twin tail Tomini Tang that was recently shared with us by RVS Fishworld. So what exactly caused this mutation of a fish with two caudal fins? We’ll leave that up to your imagination, but there’s no doubting that this is a truly rare specimen. From what we’ve been told, this fish will soon be on display at Aquarium Village in Westbury, NY.
