Have you tested your water?

No

If I did not test my water...

Do you do water changes?

No

If I do not change my water...

This parasite or some crazy animal jumped off my pleco and onto the glass.
Please let me know what to do?
Thanks in advance.

It looks like this piece of **** lice on my fish.
Do I get something like this and treat all my tanks at once?

Yeah, it looks like argulus. I’ve only experienced that once when I bought a freshly imported pair of Medusa plecos. The male had two bright green ones at the base of its pectorals. Weirdest thing I’ve seen...I plucked them off with some tweezers and the fish were fine. Never had an infestation but it’s probably better to treat the tank

Thanks so much! Should I add any other meds and should I treat all my tanks?

 

[amazontank]

Those things are totally ugly. I thought it was some parasite
Makes me feel better it's more crustacean even though it's fierce.
Should I treat all my 8 of my tanks with microblift to play it safe? Even though I haven't seen any lice in any of my tanks.

I was reading an article that fish lice don't reproduce that much in an aquarium. If I don't see anymore should I still treat to play it safe?

I can only tell you my experience...after I removed the two that I saw, I never had a problem again. It’s best to avoid unnecessary meds since it can be hard on the fishes kidneys and liver. Perhaps you can just keep an eye on your tanks or treat that one just in case
