Well, had some issues but everything looks like it will recover. The tank temp. dropped to 72 F a few days ago due to me forgetting to plug the heater back in after maintenance, though something was awry beforehand this can't have helped.
I also found some hitchhikers. I suspect this one to be majano, and if that's the case I have 2 of them.
And this is some type of stony coral hitchhiker. No idea about this one, any ideas?
