I just got a puppy, and dosed him with Frontline Plus couple days ago, the oil stays on the fur. Active Ingredients are Fipronil and S-methoprene -- fipronil 9.8% and S-methoprene 8.8%of 0.67 ml to 4.62 ml depending on size of dog. Oil residue will left on the fur will be much lower, but may still be harmful to inverts, especially Fipronil (as low as 5 pp trillion), see below:

Technical methoprene can be very highly acutely toxic to estuarine and marine invertebrates. Marine organisms are not likely to be exposed as a result of the use of methoprene as a mosquito larvicide (16). The LC50 of methoprene for fresh water shrimp was greater than 100 ppm.
pmep.cce.cornell.edu/profiles/extoxnet/h.../methoprene-ext.html
Fipronil is toxic to birds, lizards, fish, crawfish, shrimp, bees, and other animals. Minute concentrations (as low as five parts per trillion) have caused adverse effects.

If you handle anything in your tank by hand, wash your hands thoroughly after touching your pets dosed with anti-flea/anti-tick medication such as Frontline.

Funny.. you should ALWAYS make sure your hands are clean before messing around with your shrimp tanks! After washing my hands with soap, I'll wash again with just hot water to remove any soap residue :whistle:

I remember when I had a leak in my filter and grabbed a bucket from my garage to use while I worked on it. I finally got the filter fixed (not the last time it broke) and didn't want to waste about 5 gallons of water, so I dumped it back in. After I did, I got a really strong smell of gasoline. There was gas in the water also and I did an immediate 90% water change and ran carbon in my tank. No deaths! My brother did kill some of my fish a while back with soap on his hands.

Wow! Gasoline didn't even kill your livestock?!?! I guess you're really lucky gasoline is lighter than water or I think that would've caused you to restart your tank :(

It is fipronil. I'm sure of it now, had sporadic deaths in the 9g and 20L, both of which I do a lot of maintenance by hand. I have to stop giving my dog Frontline, or figure something else out. I've made sure to wash my hands well with soap, but it's not enough. Fipronil collects in the oils of the skin and hair follicles and then is released over time (up to 1 month) from the hair follicles onto the skin and hair. Frontline stays on even with bathing, swimming, or exposure to sunlight.

en.wikipedia.org/wiki/Fipronil

It's a slow acting poison, used to kill ROACHES and ants, in dogs/cats medication it's used as anti-flea/tick. It has low water solubility and tends to bind to substrates, which is probably why the shrimp died slowly overtime, and not all at once. I started doing major water changes today after spotting more CRS and even rili deaths.. infact most of my CRS / new snow white population have been decimated. Recovery rate is low. Both neocaridina and caridina are similarly affected by it, though the hardier shrimp seem to be more resistant (RCS).
