I recently discovered my fish Jasper has ick, and I'm going to the pet store very soon to buy some Aquarisol and aquarium salt...I've found two sites online that recommended the treatment. I'm curious if there is a better treatment? Also, my fish has been "twitching" when he swims...his whole body will all of a sudden move, like a twitch. Is this because of the ick, or is there something else wrong with him?
