ReefAdoRe Posted October 13, 2020 Share Posted October 13, 2020 One head open, one head closed? I am completely new to corals... and this scared me to the bone. Quote Link to comment
Murphs_Reef Posted October 13, 2020 Share Posted October 13, 2020 How long has it been like that for? Is one getting more light or flow? They don't look too bad Quote Link to comment
Tired Posted October 13, 2020 Share Posted October 13, 2020 Does it do that constantly? Quote Link to comment

They don't look too bad Just a couple of hours today - it went right back to normal. I think it just scared me mostly. I’ve only had them for 4 days now. 2 hours ago, Tired said: Does it do that constantly? Not at all, was just today. For a couple of hours. Quote Link to comment
Murphs_Reef Posted October 13, 2020 Share Posted October 13, 2020 Wouldn't worry . It could be that it's caught something to eat they can retract or go a bit of a funny shape when passing food around polyps LPS can be funny beasts.. my hammer does that.. sometimes it looks so extended that it seems to loose it's colour as well . Duncans are worse they can close for days with no reason then open back up like nothing happened 1 Quote Link to comment
Tired Posted October 13, 2020 Share Posted October 13, 2020 A coral of any sort briefly closing up, then reopening, isn't a cause for concern in most circumstances. It usually just means that either something startled it, or it's eating. 1 Quote Link to comment
Clown79 Posted October 13, 2020 Share Posted October 13, 2020 Mine do it. I often find heads will close when they are growing or about to split. Sometimes its from eating too much and just a good poop is needed. Normally not a huge concern but definitely monitor 2 Quote Link to comment
ReefAdoRe Posted October 14, 2020 Author Share Posted October 14, 2020 Thank you all for your responses 😅 I’m so nervous in having my first corals I’m watching everything like a hawk and making myself crazy. 1 Quote Link to comment
Tired Posted October 14, 2020 Share Posted October 14, 2020 Live animals can be expected to do odd things. Try not to focus so much on them, they'll be fine as long as your parameters are reasonable and nothing eats them. Make sure to keep nitrates and phosphates above 0, or they'll starve. Some people have problems from doing too many water changes because they don't know that corals need those nutrients in the water. Nitrates should be at least 5ppm, phosphates 0.03ppm, for most setups. Higher is fine on both. High nitrates are eventually harmful, high phosphates may encourage algae but aren't toxic at any level you can reasonably achieve. 2 Quote Link to comment
