I have gotten all of my adult fish, except for one, from Wal-Mart. When I got my first tank, which was 1 gallon vase, I bought 3 fish from Wal-Mart. The first night I had them, they all tried to commit suicide...they all three jumped out of the vase. I found all of them before anyone died, and put them back in the water with a lid over it so they couldn't jump out. Later that night one of them died. The next day I went back to Wal-Mart bought three more fish, and a 1.66 gallon tank, with lid.
With in a few days, all of the five had ich. They started dying off from there. Soon, I only had one of them left. I kept her by herself for quite a while before I decided to get a frog for her. I got the frog from Wal-Mart. They were together in the 1.66 gallon for a little while before I decided to get a ten gallon tank.
After I went to get the tank, I got two more frogs and two more fish, from Wal-Mart, about two weeks later. I had the survivor fish and the three frogs in the ten gallon. The two new fish went in the 1.66 gallon for quarantine. After a week they went in the 10 gallon.
Since then, the three frogs died, but the fish are all okay. The survivor fish seems to be the happiest and healthiest of them all.
In the fish story, there was about 10 other fish I didn't mention because they all died of ich within a few weeks of having them.
I also got one betta from there. He is doing good...but he has an attitude.
there have been a few times when I went into Wal-Mart and found almost ever tank infested with ich. there have also been a few times when I went in that I found one or more dead fish, in the same tank, more than half eaten by the other fish because the worker at Wal-Mart didn't take them out as soon as he noticed them. I know that because someone was buying fish out of that tank that I saw the dead fish in.
