I have tropicals! I bought a little ten gallon tank back in January and started with just a betta. I let it run for about six weeks and then added two platies. Over the course of a month or so, I slowly added the rest of my fish. I now have a betta, four platies, and three albino cory cats. They are all still pretty small and I may need to eventually upgrade my tank to a larger one, but for now they are all happy and healthy! I did lose one platy half way through, but was able to replace him and haven't lost another since.
I currently have what I think are three females and one male, but I haven't had any babies yet. I have a feeling that if I do, my betta will eat them before I get a chance to see!
I took some pics the other day, but haven't uploaded them yet!
