My Naso Tang is on the verge of dying.. At this moment he is laying flat on the bottom of the tank covered in sand, breathing pretty hard. About 2 hours ago he was fine swimming around the tank.. I dont know what has happened.
Ive tested the water and have the following.
Ammonia - nil
Trites - 15-20 a little unsure
Trates - 15-20 a little unsure
I know theyre both a little high..
the only way to fix that??
