MURPHY STRUCK...
The green and purple tipped anemone from Lemon started moving around on Friday night, and I just ignored it, thinking it will stop once it is happy. On Saturday, before leaving for a wedding lunch, the BTA was nowhere to be found. On a hunch, I checked the overflow box and there it was, hanging for its dear life.
Placed it in the sump as I was in a hurry. As a precaution, I pointed the inlet of the return pump towards the glass wall with a 1mm gap to prevent the anemone from getting sucked in.
You guessed it. I returned home to a cloudy tank with the BTA nowhere to be found
I immediately did a water change, replaced the activated carbon, and dosed half a vial of biodigest. All this while, I left the used filter sock on the bathroom floor, waiting to be soaked in bleach. When I was ready to clean up, I inverted the filter sock to find 2 large chunks of the anemone inside! This probably saved my tank from a complete crash, I'd hate to imagine what kind of damage my MP10 would do to it.
In the end, everything went better than expected. I cheated Murphy's Law twice in a day. To make the story even sweeter, I tossed the 2 BTA remains in a betta box to try my luck (there was absolutely no mouth left) and they survived! They are healing well now
