My sleeper blue dot goby had been gasping for the last 2 nights. It stays in its burrow all day long, after lights out, opens up the burrow and keeps opening and closing its mouth rapidly and heavily. I can only see it at night. I had this goby for a year now, 5.5 inches long, was very active and healthy prior to this. Its in a 100 gallon DT+25 gallon sump. Parameters are as follows
All other fishes, corals, inverts doing fine. The latest change I did was Lanthanum Chloride dosing in the overflow box to get back in control of the nutrients. I hope that did not cause this issue. Can you kindly take a look at the video and let me know? Sorry about the short video, I did not want to spook the little guy at his time of distress. Thanks in advance.
