Panacur and Flubenol are medicaments used for deworming cats, dogs and other pets. Due to the lack of missing drugs for fish tanks, shrimp keepers use them to get rid of planaria. Planaria are limped worms with triangular heading and can harm shrimp and their offspring. If your shrimplets always disappear after a few days, planaria may be the reason. They even attack full grown shrimp: The tiger shrimp showed on the pics below was jumping like crazy trough my tank. A closer look showed that a planaria had been creeping inside the body. The shrimp died later on.

While Flubenol uses as active agent ‘flubendazol’, Panacur uses ‘febendazol’.  The components will destroy cell structure of planaria and let them starve after a few days. The drugs are available as powder, pills and liquids. Powder and pills must be dissolved completely in warm water before adding to the tank. It is very important to not overdose the products and have a faithful look at the percentage of active parts! Otherwise your shrimp maybe die or will be crippeled as some people reported.

Here is a step by step guide using Panacur:

  1. Try to catch as lot of planaria as possible with a planaria trap and remove them from the tank. Remove snails while using Panacur also.
  2. Make your weekly water change (20-30%) and remove as much destritus (=biological waste) as you can.
  3. Add the medicament. Prefer to do underdosing more than overdosing! One pill Panacur KH 250 (with 250mg Fenbendazol) is sufficiant for 432 liters. Check out the table below and only calculate with the netto water volume of your tank!
  4. After 5 days change 30-50% water and repeat the treatment and dose Panacur second time.
  5. After 5 days, do another waterchange (30-50%) and filter with carbon to extract the leftover of medicament.
