Just found this thread! I love seeing pictures of all your fish! I don't have anything big right now, but I have a little betta tank set up. I think it's 2.5 gallon with a heater and a little filter. It requires very little maintenance, other than a cleaning evey now and then and some water changes. I have it set up like Bikini Bottom (Yes, I'm adult who loves Spongebob!) I don't have any recent pictures of my betta, but he's grown a lot since these pictures. I believe he is a half moon tail betta. These pictures were right after I bought the tank a year ago. My previous betta lived a nice long life of 4 years. I was very sad when he died!
