How did I kill my fish?

Could be but they are just largish frags of stuff I've had around for a while and nothing like that has happened before. If this is the case I would expect to see some impact on the other corals but even the ricordia right next to them looks fine.

Care to elaborate? This is a mature tank and a very small lion. Even with him dead in there for a while I detected no ammonia or nitrite and the corals are fine.

Sometimes when you move anemones, they **** out toxins, or so I've heard.

Just the shedding of stinging cells or a actual toxin? Interesting but when I moved the BTA I just pulled out the rock it was on and put it in the other tank so I doubt that was it either. Thanks though.

Shedding of nematocysts, or maybe just slime that coats gills and causes suffocation. I've never had it from a BTA but everytime I've moved my ritteri I've had fish losses, even when there was no visible release of slime ... it just releases invisible fish death. I don't ever want fish in with that thing again.

BTA's... pretty small though .. although I wouldn't rule it out completely, I'd be somewhat skeptical. Hard to say.

Anytime you change things there's always the risk of something ... it just seems to work out that way. Sorry to hear about your lion.

I've thought about this some more I think you guys may be right. The issue with the sea hare toxin theory was that nothing was happening with the corals, BTA slime could account for that. It is also a really big BTA (~8 inch disc when it's fully inflated) and a little tank. This could also explain my rash, I have been stung by a BTA before, I seem especially sensitive to it but stangely immune to things like torch and frogspawn that get everyone else.

Thanks.
