Okay, I tried a salt bath, and yeah, I used Inchworm's recipe on one of the pinned topics, 1 teaspoon dissovled salt(aquarium of course) in 1 cup of aquarium water....did that, and he became unconcious I guess, well he looked seriously dead!! So I quickly netted him out, and put him back in the tank, and it took a minute or so but he then started moving, and his gills moved again.....I thought the concentration might be too high, so I added another 1/2cup of water, thats 1tsp salt, 1 & 1/2 cups water, and tried him in that 7 hours later, and he did it again! I quickly netted and put back in his tank, and he's looking fine but.....Why is this happening? Am I doing something wrong? My guppy had the same salt bath recipe awhile ago, and was fine...His tail is also looking...well different...It used to have where his fins were, like black strings of where the lines in his fin was, just the parts inbetween, now nothing but black edges and a big tear left, that must have fell off too! Please help...I also did a 50% water change earlier, added little bit Melafix, and salt...
