Definately will get one next time I am near a pet store.
Well, I just got home again... I am pretty sure he wont make it till morning. Looks like the swelling has gone down and he "looks" like he is healing, however he is having an extremely hard time fighting the current in the tank even in the center. He is extremely weak and is slow. His rear fins still do not move even a little bit and they look very unhealthy. When he escapes the current he bumps into rocks and glass and is generally disoriented. Saddens me so much but i just don't know there is anything I can do for him.
Before another fish gets into the tank Ill get the sponge to plug the filter with or will make a basket to go outside the filter intake to ensure this does not happen again.
