I am
so not in favor of your doing this behind your mom's back. That's a great way to lose her trust and to cause more problems later with your fish keeping.
Your mom is probably viewing this as you taking one of her kitchen pans and filling it with dirt. Considering the cost of nice pots and pans, and the fact that so many of them are lined with a non-stick, yet scratchable, coating, I don't know if she's being completely unreasonable here. Here are a couple of alternatives:
- Ask if the problem is your using her good pans. If so, ask if you would be allowed to buy an inexpensive pot/pan from a Goodwill store or overstock store (I'm in the US -- don't know what's available in the UK) and use that for aquarium-related stuff. You should be able to get a cheap but decent sized pot from one of these for under $5. Problem solved.
- If the problem is that your mother is freaked out by rocks being boiled on her stove, ask if you can do this outside. You may have a barbecue with a burner on it that could be used. Or you could get an old metal pail, boil the water on the stove, then pour the boiling water on the rock. You will have to continue to add boiling water to keep the temperature up for the 10-15 minutes (you may be able to find a cheap candy thermometer for this purpose), and you will have to be very careful not to burn yourself while pouring water or by touching the very hot bucket. But I think you could achieve pretty much the same results this way.
- If there is some other random problem that your mom has with cleaning rocks, then explain -- note I didn't say complain -- about why you want the rocks. Do you need them to keep your cichlids happy? Do you just like the way they look? Tell her that this is much less expensive than buying rocks from the fish store and get an idea (in advance) of how much they would cost. Sometimes price makes a difference.
- If none of the above work, and assuming that your mom doesn't just have some moral objection to the existence of rocks
, then either start saving your pennies to buy some pre-sterilized rocks from the LFS or ask for them as a birthday/Christmas/whateverday present from your parents. That might do the trick.
Good luck getting the rocks you want. I hope you do, but in the long run I don't think that rocks are worth breaking your parents' trust of you. Sneaking behind her back will do that in an instant.
Good luck,
Pamela
