Think Tank was originally written for Six Sentences, although they clearly didn't get the joke of it consisting of five identical one-word sentences surrounding one very long sentence, because they ignored the submission.
After several misfires, a substantially re-written Think Tank was commended in the 2009 Leaf nano-fiction competition.
As a result of that commendation, Think Tank was published in the ensuing Leaf anthology, Ada and more Nano-Fiction.

Water. Water.

Incidentally, it turns out that goldfish actually have a memory-span of around three months, so the central conceit of this story is scientifically inaccurate. Which is a bit of a shame, really, although probably a good thing from the point of view of a goldfish.
