So, usually he is very social, swims slowly around alot, and recently he has been hiding much more than normal or resting in the leaves, he also is just kinda sitting at the top of the water,won't move even when i am near or put food in. he didn't even pay attention to blood worms! i put the end of a pen in to see if he would move *didn't wanna put in my finger* and he moved quickly away only when it touched him... any ideas? his little bulging stomache isn't worse, but its still there. maybe just him and i didn't notice till now? but im kinda worried
