How swollen looking is bloat? I have a bunch of new fish in my 75 - I'll have to weed out a lot of labs at the very least over the next year or so, but while they're all juvies, I can enjoy them. I see a few swollen bellies, but not *really* swollen, just mildly. When do I worry?

Some good information in this article.
Check for any fish not eating as first indicators. After that you may see some or all of the following:
Abnormal swelling of the abdomen, an increased respiratory rate, reclusiveness, white streaky feces, and sitting on the bottom of the tank or lingering at the surface.

You worry when there are injuries and they stop eating. Fish bellies can swell up every time they eat.

if you notice them acting weird, having white poop, and not eating then they may have bloat. Otherwise slow down on the feeding, sometimes a few of mine will pig out eating everything before the other fish can. I just spread out my feedings, and make it a little less.
