hi guys im worried about a certain guppy of mine, i have 9 guppies in my tank i dont know the gallons but i will be soon requiring a new tank as mine is getting to small for them, i have 4 females and 5 males, and one of my females tails closes at feeding time, it happened to one of my male guppies and i removed him and put him in the 3 month old fry tank and hes doing perfectly, i just dont understand why her tail only closes at feeding time?
How long has the tank been set up? Have you tested the water at all all and, if so, can you post the results? Do you know if your tap water is hard or soft? How often and how large are your water changes?
Sorry for all the questions, but we need all that information on your tank before we can get to the root of your issue. A photo of the fish would help a lot too
