Acan frag, polyps extending?

[syngraves]

Ive had a frag of Acans for about a year now. I noticed the other day after feeding the polyps were extending upward instead of the usual inflated and tenticles extended. the only change in the tank was a high salinity swing due to the person I left in charge not topping off my tank with RODI while I was away for work for the weekend earlier in Dec. salinity was 1.025 friday morning, spiked to 1.036 monday night...

Anyway I got that under control and nursing a frogspawn coral that was severely receded due to the spike. Do acans normally extend the whole polyp or is it just not happy with something? I dont know if it needs more light since it has been healthy and growing since I got it last year. started with 3 heads and now has ~10+.

That sounds like they are stretching for light

seems normal, mine (10 frags of acan) do that as well. They are greedy for food. Consistent water is a good thing.

Test your water parameters often, it isn't great to ask advise without posting your last water test results. It is like asking a blind man how you look, you would have to describe so much before any real issue is discovered.
