I have a 5 gallon freshwater tank with two little goldfish.
The tank was inherited to me, and when I got it, a third fish had been dead in it for a couple days, and was literally covered in algae. I buried the dead fish, wiped out the algae, and changed about 2/3s of the water. (It was so cloudy and dirty that I could barely see the fish.) For about a week, the fish seemed really happy.
Then, one of them, a smaller one that I had noticed eats less, has been pretty lethargic in the bottom of the fish tank. I got worried, but after about 3 days of lethargy, I spotted him swimming around happily. That lasted one day, and he changed spots, and now he is lethargic in another spot at the bottom of the tank. He has been like that for two days now. I tried poking it with the net this morning, and he didn't move places. He just flapped one of his fins a little bit.
This is my second tank. The first one was a 1 gallon with a betta I kept at the office. I had it for about one month, and my coworker helped me out with it. I have no clue about fish!! HELP! I worry about it.
