Help Me Upgrade My Fishtank!

Hi! I currently own four goldfish (Rhaegal, Jaehaerys, Drogon & Comet II), and have had three of them for several years now. I adopted them from a playcentre that could no longer care for them, and at the time the tank was more or less suitable.

However, as the oldest three have grown significantly, I now require a larger tank for them. I lost one of my original five to cancer, and another to unknown causes, before I got my smallest. I have since upgraded all my other equipment as best I can, but a whole new tank is far more expensive.

A larger habitat would greatly benefit my fish, and all but eliminate any remaining health problems they have. I am very concerned for them, and I am eager to get them into a more comfortable tank as soon as possible!

Thanks,

Rosie
