He's in a 10gallon tank. It's not heated, but that's because it's still currently almost 80 degrees in the apartment (thermometer reads about 77 degrees, but I just did a water change so that is probably affecting it - making it lower since I didn't have any room temp water to use this time.. well i did, but it smelled funny so I just used treated tap). I don't even currently own a heater to put in with him, nor can I just run out and buy one, I wasn't expecting to need one for another month or so when the heat goes off.
I do a 25-30% change one week, and a 30-40% the following week (I do a slightly better job on the gravel the second week, so I lose more water). Tank is filtered (it's a bio filter, which I hate, but it's what came with the tank), live plants, real wood, lava rock, real wood and sand bottom.. been established since October.
I do have a large bucket I could use, but I can't put a heater in it. Our floors are heated, so I don't think that's the ideal place to put the bucket either. No extra tanks kicking around (I don't even have a betta bowl...lol).
I snapped a few shots. He doesn't photograph well (aka my camera sucks), but he gets nice and active when I come close... you can see that his fins are fraying a bit, and that a few bits are missing and are quite deep. What ever is going on it looks quite mild if I'm honest. I just really love this fish :(
The spots on his lower fins closer to his body are not rot, they've been there his whole life. There does appear to be a few more than usual, I do notice that he gets them with stress, and they go away when he's happy.
I'm not looking forward to trying to catch him.. last time he jumped out on the counter mid catch.
