The Nemateleotris decora I've had in 125g DT for several weeks has always spent most of his day hovering around as expected. 4 days ago he was nowhere to be seen for the day, darted out towards the end of feeding for a few bites, and returned to his hole. Last 3 days he hasn't been seen, until I shined a flashlight in and saw him. Not sure if the artificial light made him look pale, but he was definitely breathing very slowly but steadily for the 60 second observation.
Gets along with all his tankmates, most recent addition was a rabbitfish 3 weeks ago who has shown zero interest in the dartfish. No visible illnesses on other fish, tank is currently fighting dinos.
Last week I finally began dosing calcium, enough to raise 5ppm/day, and yesterday I began dosing NO3 to 5ppm. All other tank parameters are in the normal range, as expected.
Any thoughts?
