Bred in captivity
I do love the new aquarium featured in the "High End Loft Stuff" pack. In fact, it's probably the major reason I shelled out the cash for that particular disk.
But little did I know the surprises it had in store for us!
When my sim returned from her trip to Champs Les Sims, she decided to put some of her frogs and snails into the aquarium. I think it was 2 frogs and 3 snails. I made her feed them every day, however some days I did forget and eventually the poor wee things started to die off. After she had disposed of 3 or 4 of them, I decided to click the "manage" button on the tank to see what was left in there. Imagine my surprise when it told me that there was a frog and 5 snails!
I clicked on the frog and it said that it had been caught by Amethyst Legend. Cool, that's what I would have expected.
I clicked on a snail and it said that it had been "bred in captivity". Now, that WAS a surprise! It seems that, in an aquarium, snails bred like rabbits! Not sure if it works with any other fish as I haven't tried it. If it does, it could mean no more endless fishing for deathfish. Just catch 2 or 3 and watch them multiply :D
