Princess 1 and 2

We have a beta fish that refuses to die.  It's not like I really want the thing to die, okay so maybe I do.  This is the second beta to occupy the little tank that sits on our counter.  I bought the first beta about 8 months ago for my 4 year old daughter Evie thinking she would absolutely LOVE it.  Instead we got the thing home, set up the tank, she named it Princess (I fought her on that one), and that was the last time she acknowledged the fish.  Cut to roughly 5 months later.  Princess wasn't moving in her tank and I can't say I was sad.  If it were up to me that would have been it.  But no.  Jon (my handsome, hilarious, and  VERY spontaneous husband) decided we needed another fish STAT.  I tried (not really) to talk him out of it but it was pointless.  He was already half way to PetSmart.  He came back with a new beta fish to replace the dear departed Princess, whom he threw over the fence.  May she rest in peace.
The new beta looked nothing like Princess.  Evie looked at it quickly, decided Princess had changed colors, and walked away.  And just like Princess before her, Evie does not give a shit about the fish. So here we are 3 months later with a dirty ass fish tank on our counter because I told Jon I refuse to clean it anymore.  I say when this Princess dies we should throw in the towel and let our days fish raising be done.  My husband however is insisting we replace Princess 2 when she goes because "we have all this fish food!  It shouldn't go to waste!"  Doesn't seem logical but as long as I don't have to actually DO anything for the fish, I'll go with it.  And Evie?  Something tells me she couldn't really give two shits.
