Thought Id ask here rather than starting a new thread....
Have a 200 gal display. 25+/- fish including 6 other wrasses.
I understand wrasses frequently bury themselves at night and/or when frightened.
I added this adult red Coris wrasse a little over two weeks ago. When added to the tank he seemed quite happy. Flipping over my conchs (thankfully not eating them), any shells or small rocks he could find. No fighting with any other fish that I witnessed. He never buried himself the first day and ate at the first feeding without issue. Then I started seeing less and less of him over the first week. Then this past week I haven't seen him at all.
Today I happened to see half of him protruding from the sand bed. After a few minutes he came all the way out and swam around for maybe 5 minutes before again burying himself. I haven't seen him eat for a week - typically feed 2-3 times a day. I haven't found any dead snail or crab shells. Worried he will eventually starve - and don't understand this behavior. Again, I understand wrasses frequently bury themselves - my yellow Coris, checkerboard and Leopard wrasses do it every night - but are out again every morning.
He looked healthy still but wondering why he is spending so much time in the sand and how long he will survive without eating. Anyone have a wrasse do this
after it appeared to be happy and relaxed in the tank?
