Hey Everyone!
I'm a bit of a beginner when it comes to fish, so you'll have to excuse me. I've owned
betta fish in the past, but this is the first time I've ever owned
goldfish.
So my boyfriend bought me two fan tail goldfish for my birthday, Nibbles and Jeff. And I've had bad luck from the start. About two weeks after getting them, Jeff got a water tick. I managed to trap it, and get it out of the tank. A few weeks later, Nibbles started to get what I thought was fin rot. So I put him in isolation. Apparently I was dead wrong. It progressed super quick, he became so lethargic that at times I thought he was dead. I tried everything to cure him, and nothing worked. So Nibbles died what I would assume to be a very painful death.
After Nibbles died, Jeff, who had always been very active and borderline aggressive looked kind of lonely, so I went out and got a calico fantail named Lionel. At first, the two got along swimmingly (ha ha), but as Lionel began to grow, Jeff became more and more lethargic. He no longer swims around like he used to, and he only eats when food floats down past his face. The most swimming he ever does is from one side of the tank to the other, which really isn't that far. For the most part, Jeff's fins stay up, and he looks healthy (he's not skinny or lacking in colour or anything), he's just so sad!
Lately I've been noticing Lionel chasing Jeff around and nipping at him. It doesn't happen very often, and I assume that Lionel is just looking for something to do, but is this behaviour that I should be worrying about? Is this what is causing my spunky Jeff to be all depressed? What's going on?!?
By the way, I have the two of them living in a 2.65 gallon starter tank with a filter....
Thanks!
