I know it's not a betta but I love this forum and it's been informative for me in the past so perhaps someone might have some suggestions for what to do for my little platy girl.
I have a 10 gallon tank with 5 platys in it. Last night, one mysteriously disappeared from the tank. I tore it apart looking for her and finally found her lying on her side almost under one of the decorations. I have no idea how the heck she got under it but she was.
I took her out and put her in a 1 gallon over night and added AQ salt to both the big tank and her QT 1 gal. I was almost sure she was going to die but she pulled through and is doing surprisingly well this morning, though from about half an inch in from her tail it looks like her scales are faded out in color and her tail fin itself looks very ragged. She doesn't really do anything but float here and there and then lay on the bottom... but I'm not giving up!
Anyone have any ideas what I can do to help her?
As for water parameters, I tested it last night.
<.25 ammonia, 0 nitrite, 0 nitrate, 7.6 PH
Fairly sure it has nothing to do with water quality.
