  1. Default Glofish lost color???

    Not sure where to post this, as glofish/zebra danios don't have their own forum and I'm not sure if this is a disease...
    I got 2 glofish in February and had them in quarantine until March. One was bright yellow green and one was bright purple. While the yellow green one was uniformly colored, the purple one wasn't evenly colored (white stomach area). In March they were moved into a 12 gallon Eclipse aquarium with 1 golden white cloud mountain minnow and 1 white cloud mountain minnow (since its fairly newly cycled, I wanted to go easy on the stocking). After being moved, the yellow-green glofish is now bright yellow and started chasing ll the fish in the tank. I got more plants and decorations and that cut down on the chasing alot. All the fish grew, but the formerly purple glofish lost all color. The fish is pure white and looks well proportioned, but small. The glofish will occasionally school with the other fish but prefers to stay near the lower right side of the tank and will wait for food to sink near him/her. I had heard that fish lose their color if under stress, so I moved him/her to a qt tank today and will feed separately. The glofish seems OK alone and is darting around in the qt tank-moving more since the relocation...not sure how much he/she's eating, just fed now. I don't think its intestinal, but I might try feeding a pea tomorrow.

    Parameters in the 12 gallon Eclipse:(OK, a little small for glofish, but long story for another post)
    PH: 7.4
    Ammonia: 0
    Nitrites: 0
    Nitrares: 5-10
    Temp: around 74 (both thermometers ordered DOA, awaiting #3)

    Sorry for the long post, but has anyone had a glofish lose its color?

    It sounds like stress to me. Probably because danios are schooling fish and need groups to feel secure.
    When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top... Kingfisher
    Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.

    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
    Imitation is the sincerest form of flattery.
    Dear naps, sorry I hated you so much when I was a child... Love me

    The glofish seems more active in the qt. I want to try and get him to eat more and hopefully get bigger so I can try putting him back in the eclipse and then once the qt is empty get a few more fish to up the school #. I don't want to put more fish in the qt with the glofish in case it is something other than stress.

    A 12 gallon is awfully small for an active species like the danio. Your numbers are insufficient as you know. If that tank is also bare then I think stress is the main factor.

    Totally agree with the above posters 21" x 11.5" x 17.5" is not enough room for danios.

    Not enough company and cramped quarters is not a recipe that makes fish color up in any spectacular fashion... It just stresses them out.

    The best thing to do is rethink your stocking plans.
    Gas mileage isn't everything OIIIIIIIO
    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.
