Hello

I was wondering what is the best way to propagate Palythoa grandis corals? I've never dealt with them before. Are they propagated the same way as normal zoanthids or can they be physically split?

Thank you.

You can physically split them with a scalpel or razor blade, totally or by nicking to induce fission, but they might join back together. Another that might work well is to take a razor blade near the base and nick off bits of the pedal disc tissue that should regenerate into whole polyps. Or, you can take fishing line and through consistent pressure, maybe increasing over time, force a fission. Or you can slice them horizontally and reattach the oral part.

That is interesting.  I have had these in my tank since the beginning and I get new buds forming near the base.  I never thought about splitting them to speed the process.  Maybe once I get my tank back into better health I will try it.  Chris

Thanks a million for the advice on the propagation and look forward to seeing you at MMC and hearing your presentation or speech.

Hope this isn't a hijack but if you cut them, will they release toxins?  I have some that spread like wildfire and I'd like to prune them back but hesitate that they might poisen the tank before carbon could remove it.

It's possible. That's why we always suggest in coral propagation workshops and in posts to do such work with gloves and outside the main tank and then rinse the coral well, quarantining if possible afterwards until healed, before putting it back in the main tank. Anthony had the joy of getting in his mouth. I had the joy of having one squirt in my eye while making small clusters from large mats for MACNA XVIII. Anthony can tell you what if tasted like. Here is what my eye looked like. I can't tell you how badly it burned. So I would also keep my mouth closed and wear safety glasses.

Mine regularly split off new ones at the base with just occasional spot feeding.
