Catalina goby

The Catalina goby (Lythrypnus dalli) is a brightly colored fish, primarily red with blue spots along its body. It is native to the Eastern Pacific, specifically found in the rocky reefs and slopes off the coast of California and down into Mexico. With a small stature, this species showcases a typical goby appearance, characterized by a slender body and fused pelvic fins. The Catalina goby is popular in the aquarium trade, appreciated for its striking coloration and manageable size, although its requirement for cooler water temperatures can limit its compatibility with typical tropical setups.
