Ruby, one of my ACFs, has bloated. I recently took on more hours at work and started slacking on water changes which I assume is to blame, I feel horrible. I've done one salt bath (1 gallon of water, 1/2 tsp epsom salt-30 mins per bath) a day for the past three days but so far it doesn't seem to have done much. She is able to dive but once she relaxes she floats back up top. She is mainly found floating on the surface, moving with the filter current. I'm not sure what to do. Should I medicate? I have a box of Maracyn II, though it expired in March. I can't get new Maracyn right away but might be able to pick up erythromycin or tetracycline at work today, would either of those meds work? Or would the expired Maracyn II be okay? Do you follow the treatment plan outlined on the box for fish or do you have to do a different procedure/dosage? Any help or advice is appreciated.
