Smaragdina are a hardy "splendens" type fish originating from northeastern Thailand. They are generally very hardy compare to other splenden type and can tolerate lower temperature. Betta smaragdina are known from the "snake like" facial scaling and spider web pattern on their caudal fins. These are the wild type coloration with metallic green, though smaragdinas in general tend to have higher metallic so their color shimmer differently than other splendens.
