How are you vacuuming your tank?honda237;3940971; said:i have had the similar problem, i did have an outbreak of internal parasites in my 125 which killed 8 fish, but my question is, this happens to some of my fish even after using jungle parasite meds, and double dosing, why is that?
How often do you maintain your tank?
Internal parasites thrive in organic wastes accumulating at the bottom of the tank. When you are dealing with this particular issue, whether the parasites are hexamit, cestodes or nematodes, you must vacuum the substrate thoroughly. If you have to use waterborne treatments particularly by prazi or fenbendazole, reduce your substrate to at least an inch and vacuum thoroughly. The substrate thickness will allow the meds to penetrate all layers killing the larval stages and eggs (if the particular med is quite capable of that) in the process. Boil the rest of your substrate to kill off the larva and eggs.
