Help! I've suffered massive fish deaths 1 week after combining 2 tanks, and fish have white fuzzy growths. Background:
I had 40+ guppies, 6 tetras, and 6 silver dollars in a non-planted freshwater tank. 2 weeks ago, I adopted a friend's 29-gallon planted freshwater tank, which had 2 angelfish, 6 tetras, and a bunch of other fish including 2 chinese algae eaters and 2 golden barbs. He had emptied all but 6 inches of water to carry it to my place. His tank had been stable for 2 years before this.
He said it was already well established bacteria-wise, and I filled it back with water, adding my fish slowly to the tank. The fish were doing well (I thought) until a week ago (1 week after combining the tanks) - when suddenly, all of my guppies and the 2 algae eaters died overnight. Over the next few days, a few other fish started dying, and I noticed that the dead fish and now one of the angelfishes has a clear bubble over the center of the eyeball which is spreading over the entire eye . Some of the tetras and silver dollars have spots of white fuzzy growths on their bodies and fins.
The bottom of the tank and the plants have been covered in white fuzzy stuff progressively since I brought it to my room. I use plant food.
I added a round of antifungals to the tank (second dose due tomorrow afternoon), but I'm not sure if this is the issue - 24hrs after the first dose, the cloudiness on the angelfish's eye has spread to the other eye and has gotten much worse. Both angelfishes seem very sick (lying on the bottom, not eating). I'm afraid they too are going to die.
What is going on?? Someone please help. I have left the filter on ever since I combined the tanks, and I did 30% water changes for the first 3 days after I got the tank, and a 50% change right after the first massive guppy deaths.
I've had aquariums for most of my life so I know it's not a simple overfeeding/etc issue. I have antibiotics on hand - should I use these too? Thanks for your help.
