What do goldfish typically act like in the breeding season?  Ever since it got really rainy, they've been acting odd.  We did water tests yesterday and today, and everything was good save that the ammonia was up a little to .5, but, according to the test, not enough to bother them (they've been fine in worse). It's fine now, and pH is 7, nitrates are 0, chlorine is 0, and everything else on our test kit checks out as fine.  They're eating just fine and swimming well, too.  There are no spots, streaks, or parasites, and none of them are gasping.
Yesterday, they were a bit more aggressive than usual.  Spot was chasing Sunshine and Stripe nonstop and poking them with his nose, then schooling peacefully with them later.  No one got injured, but Sunshine did bump against the glass while fleeing once.
Today I noticed that Spot has breedding tuburcles (the white spots on just his gills) and all three fish are sleepier than usual.  They're dozing in their hollow log, but come out when we come over to say hello and beg for food.
Sorry about the lengthy post, but I wanted to be thorough.  Is this what they normally act like in breeding season?

Yep, that's how they do (: About the one being chased, did you notice whether she has particularly round belly?

I found a few pictures (: Here: (Link is not visible to guests. Please register to view.) and here: (Link is not visible to guests. Please register to view.)

They are simply little white spots. They should be rough to the touch, much like sandpaper (:
And, more importantly: ONLY ON THE GILL COVERS AND PECTORAL FINS. Unlike ich, which spreads over the whole body

Mwahaha xD I have seen some pics of pregnant fish too, but honestly I can't see much of a difference d: I'm not even sure why I asked in the first place d:
