If you've had zoas melt, what do you think was the reason?

[glb]

I'm curious about this because I've read several posts about this happening. I've had good luck with mine in a 12g nano with cf lights, but I'm thinking about LEDs and eventually a larger tank, so I'd like to hear from you what you think went wrong. Lighting? Other corals? Water parameters? I love zoas and don't want to make any changes that will harm them.

They adjust to all kinds of lighting. I think the main issue with losses with zoas are from, not dipping for pest.also from blasting them with to much flow.

Mna, those things are tough to kill. I boo-bood once, and they lived through 160 Nitrates for a few months.

Mine do fine for months and all of a sudden melt away for no reason.Everything else is doing fine and all params check out.... weird...

Did you have SPS corals in the tank? What kind of lighting?

I've noticed melting from a couple reasons.

1. When algae smothers a polyp and it closes tight and browns and slowly withers.

2. Fungus causing Rapid Tissue Necrosis or RTN.

3. Pests possibly causing secondary bacterial infections.

Solution: Dip properly before adding to tank and you decrease your chances of these problems

Thanks everyone!

If I have a closed polyp in the tank that's been there for a while and then closes, should I take it out and dip it?

Flow was a prob I had but found the right places and all do great, even melting ones I've moved to more flow and came back, my lip trick!!!!!

Yes if polyps are closed dip them. If the polyps are covered in algae I would do a peroxide dip. If they are just not opening then do coral RX or similar dip.

Occasionally zoas do melt for no reason. I think is the same for every other type of coral. Can't tell you how many chalices I've lost
