Do read the article and follow the link to Science. It is really interesting and not really helpful to creationists.
To summarise:
HSP90 canalises development - when it is suppressed, the fish are more sensitive to genetic variations.
When the variations are expressed, they become available to selection.
Eventually the fish reach a state where the new form is stable even when HSP90 is working. But it is evolution that gets them there.
Oh, creationists can try to use it in their excuses, but all it is is a new way in which evolution can work. It doesn't actually demonstrate anything which would help them.

Whatever the number is, 1 or 5, it doesn't really matter. It's way to short to call it evolution. The transformation itself happens quickly, so the question is not if the fish is evolving from normal to cave-like. It's not. Question is how the whole mechanism of beeing able to switch evolved.
The only part which isn't evolution is the unmasking of the hidden ("cryptic") traits. If you disagree, I'd like to see some more details and argument. What takes only a few generations? Under what conditions? By what mechanism? And where does the article or any linked article say so?
