I don't have quite that problem, but completely understand. My mom is starting to not like the idea of how much I want to spend on a betta. And she said 'Why don't you just get a bowl.' I just told her its my money I'll do what I want with it. Hopefully she lets me lol though she knows I really want it, so I think I shouldnt have to much problem, so yeah use your own money if you have it. I think it would make it much easier. That and I like the idea of mixing gravel, I was actually considering doing that with my tank when I get it XD
I pay for all of my fish stuff. My dad will occasionally buy a fish for me if he's with me but that's it. You could always sell it online or keep it in bags. I don't throw away anything that I'll probably be using later on. You never know, you might want to go back to white.lol
For instance, I'm short on cash but I think I'm going to need some Jungle Fungus Eliminator and Maracyn for the rescues (and Demetri who has fungal fin rot >.<).. so this weekend I'm going to mow the lawn, completely clean all the litter boxes, and do whatever else my mom wants in exchange for buying me the medicine (and a heater I hope).
Even when my parents are short on cash I can usually get a little by coming home and doing odd jobs.
I'm 19, live on campus, but only about 30 minutes from home due to a lack of car (I go home every weekend), and my mom will buy me whatever I need... My dad didn't understand my "obsession" ("it's just a fish" mentality), until my mother reminded him that a grandFISH is cheaper than a grandCHILD. :) Perhaps using that as a point would work for you?
Me? Talk about grandchildren in front of the parents? I'm 15, that will bring me murder, LOL. When there's anything involving children/grandchildren, they get way out of line. They're those kind of parents... no boys! Haha. (But I have male bettas. Ooh, rebellious? Lol ;) )
Kiku - It's just a fish, it's just a fish... it's always the same thing over and over again! Lol
1f2f, if you mean trade by doing work for the parents, my parents only want me to study... they don't want me to get a job and "be distracted from my schoolwork." And my grades are pretty decent, the important part is to not let it drop, lol. I'll definitely find something though ... hmmmmm... man, my parents are crazy. lol! (shhhh)
Herbwin, I probably will use it later for something. I still have two 1/2gallons from a year or so ago (ahhh, the beginning of the betta hobby) that look like I can have fun with them. I have about 7-8 lbs of gravel in my 5 gallon tank. I am planning to get another tank over the summer... so I'll definitely try mixing the gravel once I get black gravel.
Bloo, they just flat out don't want me spending money! haha
a123, My mom is only content with my tank because she thinks it looks pretty. Hahaha, and my dad finds it soothing. But "another one? NO." Lol.
Starbright, my christmas money died on me long, long ago, LOL. My birthday has yet to come so I have to wait on that...
With my hamster stuff (not fish stuff... yet, but that'll probably change soon ;) ) When I get something, then after a while decide I don't need/want it, I typically keep it in storage, and after a while, it does come in handy.
You could say something like "Mom, my fish is super stressed by the white gravel, and black gravel will relieve the stress, becuase betta fish in the wild are used to darker places. If I don't get black gravel, he'll become stressed and sick, and it'll cost even more to get the medicines and all that." ... I don't really know if it'd work, sometimes things like that would work with my mom, and technically, it's almost true. XD
