I am sorry I cannot explain to you why your parents react as they do, it is not the way I as a parent would be,however they have their reasons I suppose which at the moment are beyond me.

A little fish would be such an easy pet to take care of, and it sounds to me like you are a responsible young lady.

Unfortunately as you still are under their roof it is as Kelly wrote a fact you will have to respect their wishes for now.

I am sorry you are upset, and I do wish you could get a simple answer to your question, one that would come from your parents.

Do as other's have suggested, enjoy other's pets, and do some volunteer work, which is very rewarding.

Good luck.
