Just wanted to know what may cause Zoo's/Polyps from opening up? I have numerous colors etc. some open and some are closed. The water is good conditions just curious Thanks
Many things come into play. Please list your current temp, Ph, NH3, NO2, NO3, SG, Alk, CA. Flow has a lot to do with it. Lighting is also important. Lastly, do not discount a naughty fish in there nipping at them. What is currently in your tank?
I would like to hitchhike here....I just got some colonly polyps myself...had them for 5 days...some are open, some aren't. I thought I say my mithrax crab eating some of them!!! Is this possible? Do they have an affinity for this? The ones that are open look great btw.
Nate, I'd give it some time. If I do a little aquascaping and move the rocks some of my zoos are on - they wont all open for a little more than a week - sometimes two. Give it time - if you've got more than 80w of lighting they should eventually come out of hiding.
However, if they've been in there a month and they're still closed - I'm surprised they've not perished and withered away.
