Toxic effects of wounding Caulerpa

[canadawest]

I harvest my grape caulerpa at least once per month for the past year and never have had any ill effects observed in my refugium or main display.

I usually pull a couple big handfulls out by hand, not sure how much I actually sever during the process as opposed to removing whole.

I'd have to suspect that a WHOLE LOT of caulerpa would have to be severed in order to produce enough toxins to cause problems severe enough to kill a fish.

I'd be looking elsewhere for the cause, as this just seems to me to be a bit of a stretch.

Just my $0.02
