I have a 125 gallon tank with three L240 vampire plecos , 2 males and 1 female and about 12 other community fish. My plecos are all about 6" long and eating fine. I did a water change a week ago and one today and from last week my females belly has gotten fairly large. Could she be holding eggs or should i be worried about an illness. I am currently looking on line about illnesses but would appreciate any feedback of what i should do next.
