A family member sprayed raid near my tank, will it hurt my oscar?

I suppose it depends on how much got into the water. I really have no idea how toxic this stuff is to creatures other than insects (I'm assuming that raid is a insecticide? It is over here) if it was just a little spray, and the fish are showing no signs of distress, I shouldn't worry too much. Might be worth while doing a water change to be on the safe side if you are worried and don't know how much was brave

I think raid is a fly spray. Fly spray is bad for fish and apparently can kill fish. Most fly sprays say on the can to cover fish tanks. So does your tank have cover glass and more importantly does it have a hood

If your tank has a hood i wouldnt worry about it too much but i would do an extra water change now just to be sure

If your tank doesnt have a hood then i would be very concerned. Some of the spray could of got into the tank and as said the spray is poisonous. I would daily water changes for a week or so starting ASAP to try to dilute any that got into the tank. When you do a water change try to do a big percentage as possible up to 50%. Try to do 2 or 3 changes for the first couple days. This may sound excessive and it probably is but my attitude is water changes are easy to do and it is better to be safe than sorry

This brings up a good point, dont use fly sprays anywhere near your fish tank. If you have a problem with flys then try the old fashioned way and use fly paper

OFL i cant remember if the use of fly sprays are mentioned on the site but if they arent them maybe you could put a warning on the site
