Stupid fish

So I casually mention that I'm pretty happy with my little fish tank (set up and abandoned by Dan and Peter, taken over by me). And wouldn't it be fun to have a bigger tank so I could have more fish. Well happy freakin Mothers Day here's a new tank to do with your kids. Great, so I have been putting Peter off for a few months now but it's driving me crazy so today I decide to get with it. We went with a whole beach theme, nice pale gravel, tropical decorations. As I wash the gravel I note and point out to Peter all the cool little shells and pieces of Coral in it. Just like on the beach. Once I get all the water in (Like ten buckets later) I'm reading the instructions to something or the other and It hits me I've read something before about using coral in a freshwater tank. Oh Shit, not good for fresh water makes it too hard. So now I have to take all the water and gravel out and start again. I wanted to go outside and scream. I do like the fish don't get me wrong but it's getting expensive and I really have better things to do like laundry and dishes.
I'm going to bed now maybe I'll tackle it tomorrow maybe I won't.
