Please help, I have 135 ltr tank with spawning rams, phantoms, cardinals and 1 zebra loach. I have lost 2 zebra loaches and a couple of tetras already. It looks like skin flukes as the Male ram has about 6 or 7 around his fins and body but nothing around the gills, the female ram has 1 just below her mouth. The worms look like twisted bits of cotton. I picked up a UV sterliser and treating with cure ex this is day 4 and the worms on his fins look like they are getting bigger, can anyone suggest something I can do, I do not want to lose this pair or the rest of my tank if I can help it.
