begin2117 Posted February 16, 2011 hybroids. (sp?) i heard they can sting corals. i have some but they arent that much of a problem, they just kinda stay in their own area of the rock... they floresce green sometimes too. Quote Link to comment
crailtap25 Posted February 16, 2011 Colonial hydroids. I have them too and they don't really harm anything unless they start spreading. Good water quality will keep them away Quote Link to comment
FreakShow Posted February 16, 2011 They can spread. If they are in a place you can easily chip the rock off that they are on I would do it, otherwise don't put a coral right next to them. I have had them spead and invade a zoa colony and the zoas would not open where they touched. Quote Link to comment
kotlec Posted February 16, 2011 Yes I can try reach them. But dont they release any "babes" during my invadion like apitasia do? Can it be filterfeeder ? Quote Link to comment
