added a teeny bit of salt(one teaspoon), cut back feeding a bit, upped the filtration(added a hob). my mom was going to go buy medication but figured trying the salt thing might help(she did some research on her own and that is what she came up with. she asked me and i said might as well try it). i know everyone is going to say salt doesn't do anything but it seems to be clearing up the infection/injury. they now have 2 hob's and a sponge filter. so probably at least 25-30g worth of filtration.
