I went to the store and got aquari-sol. he seems slightly better but still very sick. I figure I may change like 30% of the water tommorrow morning then change to aquari-sol. I don't like doing this mid medication. If he would just eat I would know he's on the mend. He comes out and goes through the motions like he wants to but he doesn't. I also got tank buddies. I am not going to use these all at once. believe me. I just want to know which is best at this point
