daisy coral not eating

[aaronttan]

Hi everyone,

 

Aaron from Sydney here....I have a 7 gallon nano...everything's doing fine except for my daisy coral (duncanopsamma).

 

I've noticed recently that his polyps have been looking quite swollen and he hasn't wanted to eat anything. He spits out the pureed food I usually feed him whereas he used to eat it up with gusto! He also used to take frozen brine shrimp and now he's not interested.

 

Water parameters are fine. I am really religious with my tank maintenance doing 10-20% water changes 1-2 times a week.

 

Actually he looked a little better this afternoon when the tank was due for an RO top up. The salinity is measures between 1.023 and 1.025 normally....could it be that he preferes a higher salinity?

 

Thanks in advance guys. Aaron.
