Hello all-About a year ago I added a few more Black Skirts to my tank that were all pretty small and about the same size. Two of them grew to what I have seen is an average size but one of them stayed very small. It is not even half the size of the others but looks basically exactly the same. I am hoping someone out there can give me a clue as to what is up with my little fishy. Any help, suggestions, etc would be very much appreciated. Thanks in advance!!
