Guppy losing colour

    thumbnail_IMG_2552.jpg Hi,

    About a month ago I noticed my guppys tail was turning white and her body now too. She is a sunburst with yellow and orange colours. This happened about a month after she had babies. She has been isolated for a month and I would like to put her back in the main tank but don't want the other fish to get sick. Any ideas what it could be? Nothing else is wrong with her, behaviour is normal and is eating.

    Generally, color loss can be a sign of stress. Are other fish causing stress to the guppies - chasing or nipping them? What are your water parameters?

    Are you noticing the color loss all day or just in the morning? It is common for fish to become rather dull overnight to avoid predators, but in the morning, when the tank lights come on, they should color up rapidly.

    Unless part of the tail is actually missing, it's safe to put her back in the tank with others, but if it's just some discoloration, then it could just be stress. Again, what are your parameters in the original tank (not the one she's in now)?

    Wishing you and your fishies the best!

    The male guppy was following her everywhere she went for a while. I got the water tested at Petsmart the other day and they where perfect (I forget what they were though). She has been white all day everyday for the month.

    It couldn't be Columnaris or saprolegnia?

    If the male Guppy was following her everywhere, they were probably breeding :)

    I'm pretty sure it's not Columnaris or Saprolegnia, but if you're really worried, here's a couple links that might be able to give you some more info:

    Welcome to the forum, by the way! ;D

    I wouldn't be so quick to jump to conclusions. Does she have fluffy white patches on her body? If not, I doubt columnaris or saprolegnia.

    What is your tank size, stocking, and parameters?

    EDIT: Wow, I totally skipped over what you said about testing your water at Petsmart. That's not the best idea. LFS often use test strips that are expired and inaccurate, and have a much different view of "perfect" than us fishkeepers do. I recommend you get the API Freshwater Master Test Kit. It allows you to test your own water accurately.

    Exactly, the picture doesn't show if it's fluffy or smooth.

    Yeah i was just worried it could infect my whole tank. I have a 5.5 gallon with 5 baby Guppies and 3 frogs (I know that is more than I should but I was told it was fine and I've never had problems with it.

    The test strips were good, they tested it 3 times to make sure (I work there).

    It is smooth, looks like white out was put on her.

    I see her tail turning white, but not the smooth white patches you are describing. Could you try to get a better picture?
