Hi everyone my name is noelle and I have a 40 gallon freshwater tank. This past week has been mayhem with my tank and I can’t seem to get a grip on the problem. This tank is relatively new. I did a new setup about a week and a half ago and ran the cycle for 48 hrs before adding fish. I’ve had 8 fish die. I was fairly convinced it was ich that had taken the tank by storm. I did a 4 day treatment with pimafix with a 25% water change each day as recommended to me on another forum. The fish have certainly improved but I’m clearly not out of the woods based on how they are acting. Most are maintaining at the bottom of the tank which is abnormal especially for the dwarf gouramis. My Colombian tetras have cloudy eyes and my cherry barbs are behaving as if deprived of oxygen, and my two Botias are laying basically still outside of small movements every few minutes. The water is testing perfectly with test strips and I have a 10 in air stone running in the tank plus an additional down line just bubbling for a bit extra right now as they struggle. I did a 40% change this morning with a tbsp of aquarium salt (since the tank had a previous level I only added 1 tbsp) stress coat and some accuclear. I can’t for the life of me figure out what is wrong but I really don’t want to lose any more fish.
