I can easily pull the frag off the rocks and do it in a small bucket but the hydroids seem to be all along the stalk of the zoa how would i go about glueing that? I have gel super glue in hand but no calc powderYou don't want to get it over the zoa. Turn off water pumps allowing gel to harden 2-3 minutes. Superglue has a nice small applicator, which will allow you to target the hydroids
Was just trying to find out if hydrogen peroxide would and all I can find is people saying to try it I guess it couldnt hurt to try. Been googling non stop and I am pretty sure they are branching hydroids but i have had this frag for months got it when it was one head so these must have come from the water columnIf it’s a small contained area, I’d turn the pumps off and either remove carefully or glue over. Your best bet is snuffing out whatever is there if it’s a small area.
again I don’t know if it reproduces in the water column, this is assuming it spreads locally like the bigger colonial hydroids.
hydrogen peroxide dips with a q tip may kill off the hydroids on the zoa. Double check that tho.
