Brad!

I agree with brad that it seems suspicious that if it was heat, why wasn't it happening last year?

I can't take the time to read all of the ramblings, but I have read the main points. Sorry if I have missed anything important.

Yes, my tank temp has been higher lately.. goes up as much as 84 at the hottest point of the day and then drops to 80 at night.. I have seen no changes in any other behaviour in the tank. Would I be safer bumping up my thermometer so there is less of a swing when lights go out?

I do see that temp could have been the cuase with some of these deaths but something else seems to be happening here too.. gotta run..
