If you are actually quitting because of your fish tank then...of coarse it's bad for your fish! Really really bad. You definately should quit, your fish will thank you!
...or smoke outside if quitting isn't an option at this time.
You'll find you smoke less if you make yourself go outside whenever you want to smoke and you and your house will smell a hell of alot better for it.
I would watch them closely for any signs of silliness or munchies!
Seriously, though, I don't allow any kind of smoking in my house. Even if I did smoke, I'd do it outside. I have cats as well as fish and wouldn't want to expose them to any kind of toxins unnecessarily.
I've heard of getting dogs and cats baked, but fish?!?! You might be on to something. Might be able to get that finicky eater to start eating and fatten up and grow!!
