    Mark, talking about pest. I had messaged you about a week ago, about an anenome out break. I had accidentally bought a green bubble tip anenome, thought I was buying a green bubble coral. Well I put it in my system but ended up only a few days later, getting rid of it and shortly after, there were little anenomes popping up all over. Now these sprouts have a green base with kinda brownish tentacles. No matter what, I’ve tried to no avail, now there’s thousands. Any suggestions, anyone?

    Mark are there no fish that eat all these pests so we can do things the natural way, Also, were do you get your fab tee shirts

  • steve…no fish that eat the pests off the corals. Plenty of fish will eat them once they are dislodged from the coral and in the water column.

    Shirts come from this place

  • Sounds like a Majano anemone, not a bubble tip. Majanos are bad. Remove any rock you can that has them on it.

    I’ve used time-lapse photography to find pests. Set up your camera on a tripod, set the timer to 30 second intervals and then, review the shots in something like Lightroom or similar. you can page from pic to pic and spot things like AEFW, Zoa eating Nudis etc. I even found a GIANT snail-eating flatworm (4″) this way. Don’t ask about getting the flatworm out. Let’s just say that timing and a long, thin siphon tube worked – but not on the first try!
