Good to know about building/recovering. I'll definitely be experimenting with that soon. I'll have to post some pics when I do.
Crash fish don't worry me too much, they don't deal enough damage to kill you, so as long as I don't have to deal with too many of them I don't worry. I've tried to kill them with my knife before they go off but either I'm not fast enough or it isn't possible to do.
