Ok, so... Prior to Christmas 2012, we had no fish tanks and zero interest in keeping them. Then on a whim my sister bought my toddler son a *tiny* tank as a gift. We got a goldfish, discovered the tank was far too small and upgraded. Then we went full steam and got a 250litre tank which I thought would be the limit and I'd be satisfied. Turns out, I've only whet my appetite. So, here I am, sitting on a dining room chair, watching the fish in our beast (the big one), dreaming of another tank to fill with wondrous creatures. Husband agrees, hopefully by November, we will have another, albeit smaller, new tank to fill. So, here's my point. If you could have any fish, in any combinations, with zero restrictions, what would you fill your ideal (wishful) tank with?
