| || | " My tropical fish died"
I have a new 20 gallon aquarium which I set up and let it sit for 3 days, after doing this, I put in my fish that I had in a smaller aquarium, and I put some of their water into the new one. The fish I put in the 20 Gallon aquarium was 5 guppies, 3 swordtail's and 2 neon tetra's which I waited until later on in the afternoon to add. The next day, when I came out to feed em, they were all dead.. What did I do wrong...
