I have a 10 gallon aquarium and have one medium size goldfish in the tank. About a month ago, I decided to purchase couple of live plants. Once I got it, I simply planted it into the tank without cleaning the plants. About a week later, I saw a small snail. I was surprise to see it but not alarmed. Then, 3 days later 2 more. On a closer inspection, I saw many what looked like snail eggs on the plants and on the glass. Today, I was looking at the tank and found many tiny snails. Plus, it looks like my gold fish was bitten by something. On one side of the fish, it looks like something took a big bite of the fish. So, is my goldfish of 7 years doomed and is going to die? and Will I be able to get rid of the snails out of my tank? I think I have snail infestation...
