I have a pair of Bolivian Rams. Both have camillanus (Red threads protruding anus). I treated the tank with Fenbendazole Wormer Plus three times in the last two months. I put a sachet for 50 gallon into my 30 gallon tank as it says in the instructions not to under dose. It just does not seem to work. Any other ideas people. It killed all the pest snails in my tank so it had a positive effect
Maybe a dip or bath treatment?
