Hey guys I just bought a highfin blenny for my 20gals. Now I have him and two other fish which are a tigerwatch goby and a mandarin goby. He is all black with few white stripes on his head, not sure what color his fins are. I noticed yesterday that when I put him in he was breathing heavily. When he was in the lps, he looked fine. I thought he will not make it through the night because he looked like he was dead, lying on the sand bed looking lifeless. Today, he is alive but hiding in the lr and wouldn't come out. I have never had a blenny before or seen one like this, is this his natural behavior or is there something seriously wrong with this little guy?
