Hey R2R,
So, I added a yellow watchman goby to the tank from my LFS two weeks ago. He immediately found a burrow and was acting pretty normally from the start. I noticed a very tiny transparent patch on one of his pelvic fins (can't get him to pose for a picture of that) shortly after adding him to the tank, but it didn't seem to worsen, and seemed likely to me to be secondary to trauma from transport/movement from the store to my tank or perhaps unseen at the store or from burrowing once added to the tank. Fast forward to tonight and I just noticed a very small transparent patch on the rear of his dorsal (?) fin proximal to his body. He hasn't been in a burrow much for the past week or so, but seems content hanging out on the bottom of the sand bed. He eats brine, flake, and mysis like a champ every time the tank is fed, and seems overall very healthy and happy. Other tank mates:
- two clowns who are not aggressive
- cleaner shrimp
- 2 pom pom crabs
- bangaii cardinal
- firefish
- a candy pistol shrimp who I've only seen once in the past month
Tank is only about 2 months old, but water parameters are stable with undetectable ammonia, undetectable nitrite, nitrate 0.5-2 depending on the day. Phos 0, Alk 7.6, calcium 420, magnesium 1260. Salinity 1.024-1.025. System is a RedSea Reefer 250. Unfortunately, I do not have a quarantine tank, and did not dip this guy before adding to my home tank. It is possible I have simply not noticed this transparent patch before, but am concerned as I don't want it to worsen or spread to other tank mates. I do not think it is trauma as it is so close to his body and the ends of his fins do not show any signs of damage/rot. Everything I've read about these guys says they are very resistant to disease, and with his eating well and no other concerning signs I'm hopeful this is just a normal variant. I also don't want to miss something simple that could be treated early. Any ideas? Thanks in advance for your thoughts.
