I don't know what I did wrong. But I have a few that survived..... I used fish bendazole (fenbendazole)Ended up doing a 50g wc. Looks like all the hydroids look dead, but one... All have lost their heads but one still has it. Don't know if it's dead and not lost it or what. I'll up date that latter. All corals look good so far. Did my wc at 31 hours, due to traffic. I have over 20 sps corals/colonies and maybe 10 lps.
I have only have one monti, Idaho grape that RTN a little
All fish, shrimps and crabs are doing well
