My friend's beta is very sick... and we're not sure what to do. There seems to be some fin/tail damage, probably due to tail rot. Also, there are fairly large open wounds and we're not sure where they could have come from; the scales are missing and you can see the white flesh. On top of all that, he refuses to eat and floats around the top of the bowl all day long. We got some antibacterial medication and aquarium salt, mixed the medicine with a gallon of bottled drinking water and recently started replacing half of the water in the bowl with this mixture on a daily basis. Is there anything else we could do? The fish has jumped out into the sink several times while my friend was changing the water, but these wounds and damaged fins weren't from these accidents. Could these events have caused enough stress on the fish to cause him to catch some kind of disease? Can anyone diagnose this beta if indeed it is a disease. Here are some pictures but they are kind of bad quality. I will take some better ones later and post them up. Someone please help! She really loves this beta and I'd hate to see anything bad happen to him...
