Injury or infection?
This Twin Spot goby been in my Reefer 250 for about 2 months. This redness around his eye showed up 3 days ago, he has continued to eat mostly as normal. The other eye is normal. Tankmates are Royal Gramma, tiny Hawaiian Whitespotted Toby, and a Tail Spot Blenny. I haven't seen any aggression since arrival. Other fish are acting normal as well and show no signs of infection.
