foolish move

I moved some plants in my tenner, on a day that wasn't water change. Just a few loose crypt parva back into place-

moved this tiny crypt willisii over to front center-

tied a few errant buce onto a stone

and wriggled them back down into substrate. I forgot I ought to do this only when siphoning out some of the mess. It didn't seem to kick up much mulm, but the cories looked distressed and were flashing. I did a small water change the next day and reminded myself to be more careful next time.
