Clownfish acting sick...

I've been gone for two weeks on vacation, my mom fed the fish while I was gone, and got back last night to find my six line wrasse missing (presume dead) and one of my perc clowns acting sick. Coloration looks fine, no spots that I can see. Stays primarily near the bottom corner during the day and at the top behind the water return lines at night, almost floating on the surface. Breathing heavily, and at one point it looked like stingy poop or something was coming out of her, guessing some type of internal parasite? She's my first fish and has been healthy for a few months. My second clown still seems fine, and will come over to her and swim all around her and rub against her from time to time, doesn't look like harassment though. She'll perk up a little and swim around a bit with him when he comes over. I'm only guessing at their sexes, they were exactly the same size when I bought them and are still pretty similar in size. Any ideas what could be wrong? One last thing, the day before I left I bought some live brine shrimp to entice my canary blenny to eat, but everyone ate some. Don't know if that might have contributed. Thanks for your help.

 

And before anyone asks I ran the full spectrum of tests on the tank, all levels are right on, except calcium was a little low (340), and salinity was a tad low at 1.022.

I also found out mom was feeding them everyday, and I would assume way too much, so could it have been a case of overeating?

 

keep a close eye on them my clowns acted like that then they broke out with ich and died

good luck and keep us posted

ps i found it easier to see ich with the acylics on

 

Crisis averted, looks like it was just constipation. LOL Shes back to normal now.
