One thing we are allowed though are fish! Even though we can't take them on our country walks we've really been looking into having a good sized fish tank. We used to have goldfish but I would love a tropical tank. The fish are so much more interesting and pretty. I had tropical fish when I was a kid and I loved the little neon fish that zoomed around the tank.
With having a tropical fish tank they become slightly harder to look after than just gold fish. There has to be a good balance in the tank to keep the fish healthy. I also found the hard way as a kid that you really shouldn't over feed them!
It can be confusing setting up your first Tropical fish tank as there are so many things you have to consider. You need a heater to keep the water warm and a filter to keep it pure. It's best to shop at specialists like All Pond Solutions to make sure you are getting the correct items for you tank. Most of the time having a tropical fish tank is about looking after the water rather then the fish. Their environment has to be perfect for happy fish!
We are planning on buying the tank soon which means it's still going to be a while until we can actually buy the fish. You have to let the water settle for weeks so it is something you have to be prepared to wait for.
