Thought I'd share one of the stranger things I've seen in a while with my tanks. I had to take apart and put back together both of my marine tanks today to move them elsewhere in the house due to possible floor issues. I decided to have a look in the reef's canister filter to see if it needed a clean, since it hasn't been opened in ages and I didn't want it to blow debris all over when I hooked it back up after being jostled around. Cracking open a marine canister filter that hasn't been opened in months always brings with it the chance of surprises and I've seen everything from entire chambers converted to live sponges to mussels burrowing into filter media, but this is a new one to me: a tiny bubble tip anemone. Must have just been eating particulates passing through since there's not a hint of light that gets into that filter. I have other BTAs in the tank and have been propagating BTAs for probably around a decade now; never had issues with this particular canister intake injuring an anemone in years of using it and never seen any evidence of injury on my current nems. Perhaps a very small stray bit of tissue from a split tore off in the current, got sucked down and managed to heal up - but it would've had to survive the impeller chamber to get where it was when I found it. I've plopped this strange micro BTA back in the main tank now since I can't think it actually likes living in the inky dark, so probably I won't see it again for months (if I ever see it again) since it's only about the size of a pea.
