Keep a close watch on the other fish to see if they develope any similer sighns. At first it may sound like gill flukes, if that in fact is the case then i reccomend Fluebenol 5% I am at work and do not have the dosage with me but it will work the best and is the most gentle on the fish. Stuff like formaldahyde is very strong and may kill a small fish like an Apisto. Get a copy of the TFH book Hand Book Of Fish Diseases. It has Info on Fluebenol 5% it will kill both strains of flukes and info can be found in this book. You can find this drug from FTFFA mail order. I will e-mail you the further info when i get home.
