have had a solar fairy wrasse for at least 2+ years. he usually always swam at top of water column and wasn't a hider. About 3 weeks ago i added a sailfish tang to the tank (150 gal) and all was fine. A week later i notice out of know where the wrasse isn't out anymore. I found him hiding in the rocks. comes out sometimes with food and eats a bit then back to the rocks, all day. Been about 2 weeks of this. Did the sailfish scare him or something??? he hasn't chased the wrasse or anything neither has anyone else i can tell. Any idea? Nothing else new or changed with tank and no swing in parameters. the wrasse was a good 3-4 in in size 2 so not small.
