i just bought another gsp that ar in pure freshwater today, my tank sg is 1.024 so i did dripping for about 4 hours with a air pump in it. the sg of the water in the is the same with my tank after dripping and it doin fine when in the fish bag but when i put him into my tank he seem like doesnt feel well like his stomach turns grey and his body is kinda shaking sometimes. anything tht i can do for him? i dont want him die lol.
