Help, sick fish maybe?

WTF...

So tonight, not much having changed... two monos die.

One starts swimming sideways, being weird, darting around, then BAM, upside down cold/dead. Like a massive heart attack. A quick spaz then instant death.

About 20 minutes later another one.

We originally had the three puffers. Then a month or two later the 3 monos for a few weeks then added two more about two weeks ago. I'm pretty sure those two additions are the ones that died today.

I'm not sure how to describe the current tank activity. Maybe they're doing better... maybe not, it's hard to judge right now.

The two GSPs seem almost completely normal (I think, again, tough to judge).
