Well, he seems alright now. The jar had a betta-sized groove all the way around, if you can see in the pic (at the bottom) so he lies in there a lot of the time. However, he is eating, and looking more active. the jar is doing well, added the second bit of bettafix to it, and did a tine water change to the jar. Im hoping his fin opens up, thats whats really worrying me, and i havent had a clear reply on what it could be?
its pinched shut (his dorsal fin) and the others look like they could possibly be on their way of being pinched aswell. there is bettafix in there, so im hoping that'll prevent it? Any ideas, though?
