Effective dip treatments for hydroid infestations

Post by dripple »

Got a bit of an issue with my candycane skeleton - there's this small, white filament-like stuff growing on it, and to make matters worse, I'm losing a couple of polyps. Trying to figure out the best dip to use to hopefully kill off any pests that might be in the coral and remedy the situation. Considering Coral Rx and Revive - has anyone had any experience with either of these? Or is there something else I should be looking at?

I've had good results with CoralRx for dipping, it's been reliable for me. When it comes to dealing with colonial hydroids, I've found that physically removing the affected area or using epoxy to smother them works well - just apply it directly to the hydroids, let it sit, and then remove it once they're dead.

I'm not entirely convinced they're hydroids to be honest. They're these tiny whitish/clear filaments with a polyp on the end. I'm just taking a guess here. They're really small and look like this (photo not mine).

Got a couple on some new frags myself. Would love to know the best course of action too.

I've heard seahorse keepers swear by Panacur for this type of issue, might be worth looking into. As for CoralRx and Revive, I'm not optimistic about their effectiveness against this particular problem.

I've had success with Bayer insecticide, picked it up from Home Depot. It's killed all the pests for me, just Google the dipping directions and follow along.

I dealt with these pesky filaments before - super tough to get rid of once they take hold. Coral Rx and Bayer won't even touch them, I've tried. I've heard Panacur might work, but I was worried it'd harm other corals - it's actually Fenbendazole, which Panacur is a brand of.

Got the same issue here, it's decimating my WWC Flintix9er lemon colony and I'm getting pretty frustrated. Has anyone managed to completely eliminate these things? I'm planning to pull the rock, manually remove as many as I can, and then I'm not sure what to do next. Will a freshwater dip kill them off or is there something else I can try? Maybe H2O2? I'm removing what I can today, then tomorrow I'll be blasting the rocks with my WP40s, and removing all the detritus from the sump to try and starve them out. I'm also stopping feeding until they're gone. Any ideas or experiences would be a huge help.

I'd try using a small paint brush to apply a mix of 1 cup tank water and 6 caps of hydrogen peroxide directly to the affected area. Remove the rock and gently brush the solution over the filaments. I've had success with this method in the past when dealing with similar issues on my daisy polyps.

I finally gave up the fight where they were impacting my coral, covering them with superglue just wasn't enough. Overfeeding was likely exacerbating the issue, so I drastically reduced feeding to once every other day. Three months later, they'd vanished. After some research, I'm fairly certain these are digitate hydroids.
