I have 4 goldfish right now. They're in a 20 gallon long because they were tiny at first but now they've definitely outgrown that tank so I'm planning on building them a pond soon.
Here are some recent pictures, all taken a few days ago.

I had six but two died soon after I got them 
 
They're about a year and a half old because I got them January of last year.
I have also had several bettas and my most recent one about 4 years ago was in a 10 gallon planted tank. Originally he was in like a 5.5 that was almost totally bare and sharp plastic plants and he was kind of sickly but then I learned more about fish and it was suggested he needed more hiding places, bigger tank, etc. So I spoiled him and upgraded to a 10 gallon, bought a bunch of plants, a heater that actually worked, etc. And he thrived and got way healthier but then he died unexpectedly one day, not sure why. The tank was a lot of work to maintain though with the plants anyway so I don't miss that but I do miss the fish. I loved that little guy. I'm not sure if I have any pictures of the tank or not.
