My parents just set up their 25 gallon tank, and my mom wants (and there is no talking to her... or else I would keep it up..) to add fish. I've cycled all of my tanks before adding the fish, but there is no convincing her, and she just tells me she has no patience.
She repeats over and over that they didn't cycle their tank last time and they lost no fish. And my boyfriend says the same thing about his father when he started his 55 gallon.
What are the steps EXACTLY to try not not lose any fish while cycling? I'm nervous about having the fish die, so I want to try hard to prevent that.
Any help would be appreacited.

Thanks.
