So I got them a week ago as a bonded pair and they are the only fish in this tank. But I noticed my “male” he keeps opening and closing his mouth pretty fast? Is this rapid breathing or some kind of behavior? Just today he started to gravitate to hiding under this rock before the two would swim together and show signs of wanting too mate with the male twitching when the female comes and nips his underbelly or w.e they do. She doesn’t attack him and he submits every time ? But now I’m afraid something might actually be wrong… he’s hiding under a new cave he found and he keeps moving his mouth like he’s telling her off or something pls help
