I have a 37 gallon finished cycling. It has ideal paramaters. It only had 5 zebra danios. Yesterday I added 5 lamp eye tetras. They were all fine, but not I look and see none. After investigation they are always by the filter or by the air stone in the other corner. Is this just them getting used to it or are they sick?
