Lucille, that's what I thought because I know they are more active at night but even in moving the live rock I didn't see him also the first clown went missing way before him.
Oh and to answer your questions Jon
What sort of temps are you running?
I try to aim to keep my tank between 75-77 F
Does the temperature fluctuate at all?
Just a few degrees between the upper 70s
how often do you do a partial water change?
10% weekly and then 30% every 3 weeks.
What kind of salt do you use?
Instant ocean[i]
What supplements do you add (if any) to the water?
None
What sort of lighting are you using (mostly important for inverts and rock)?
It is a biocube so it is PC/LED
and for food, the fish eat salt water pellets
while the Starfish (and the eel when I had him) ate clams and shrimp
Yeah, the pH is normal at 8.3 currently
but I've never done an ammonia test before. Had an idea the starfish might be chomping away but I've never caught them eating anything other than their own food and occasionally if some of the pellets aren't eaten by the clown off the top of the live rock.
This is the tank when I first got it. You can see the two clowns and one of my starfish, Pancake.
