Monochrome5 Posted January 28, 2011 Share Posted January 28, 2011 Yah looks like hydroids kill them, i lit mine on fire, shoot lemon juice or boiling water at them asap, they spread. they suck They're hydromedusa, the medusa form of a colonial hydroid species. They aren't really a bad thing... but they are annoying. They won't hurt anything, but if they morph into their polyp form they can irritate corals. They sting, but not strong enough to do any damage. They're terrible swimmers, so if you knock them off the glass they usually get sucked into the powerhead and minced. If you see any polyps forming you can just pick them off or glue them or whatever you want to do to kill them. Link to comment
GokesReef Posted January 31, 2011 Share Posted January 31, 2011 I had 2 or 3 of them when I first started my tank.. died off in a month or so and haven't seen any since. I usually whacked them with the magfloat as I went by. Link to comment
