Fritz Expel-P 20 Count

not happy with it killed all my crabs and cleaner shrimp but doses kill worms like it send . big lose of clan up craw .

I had some new fish added to my display tank and used this medication as a precaution. It worked very well, I follow the directions on the package, make sure windows are closed and plant lights are turned off during treatment period. I have freshwater shrimp in this tank and it did not harm them. Important note:this medication is hard on fish, and they may seem a bit “weaker” by the end of treatment. Once you do a follow up water change though in my experience my fish came back much stronger than prior to the meds. No sunken bellies, great colours and feeding response. Also, this does not replace good tank maintenance. Keep your tank as clean as possible, that alone can prevent 99% of diseases from occurring.

Bought guppies from Petsmart and every single fish was sick with worms and other parasites. Unfortunately it made its way to my healthy fish. This stuff works gently over night and did not hurt my shrimp or mystery snail. Snail was uncomfortable so I would keep an eye out or just remove them overnight. Light sensitive but does not need to be blacked out. 24 hours later all stringy white poop and clamped fins are gone. They started eating as normal. Total fish saver. However, it only paralyzes worms so they can be pooped out by fish. You must remove all white poops they expel during water change because they are still alive.

Bought to try in my aquarium as I had 1 fish who had worms in his bum. Treated the tank as directed, and within a coup days, I couldn’t see the worms anymore, did the water change as directed, and then treated once more as instructed on the box. Has been nearly 2 months and all are healthy. Note, I did loose 2 out of 20 Cherry barbs which developed dropsy, not sure if maybe the had worms and couldn’t pass them, but still over all was very satisfying with this product. The fish who had visible worms was a one of our 2 Bolivian rams. He become very distant from the rest of the tank and was secluded to one corner. After the worms were gone, he’s now very active and healthy. He didn’t grow much after due to the timing in which he had the worms he lost a lot of his growing time.

Ordered this as research showed it is one of the only parasitic medications that does not harm inverts when used as directed. Purchased some endlers that apparently had camanellus worms (red worms) that snuck past quarantine and were introduced to a community tank with scaled and scaleless fish, a shrimp colony and mystery snails. Soon as the parasites were noticed, I followed the directions on the package with the secondary dose and did a full tank black out during treatment, except during feeding time as the instructions mention this med is light sensitive. Was also dosing Artemiss and Herbtana at the same time to cover my bases just in case something else snuck through. All residents survived treatment and are thriving. No damage to inverts or scaleless fish, even the pygmy cories who tend to be a little delicate. 10 out of 10, will be ordering again to have on hand.
