Yesterday I noticed her belly was a little bulgy, but I figured she had just eaten too much. When I fed my fish today, her belly was even larger and I can see some darker coloration inside of her belly. Its more of her breast than belly that is swollen. The smaller of my fish is always trying to be close to her, twitching and flopping around. I don't know if this is mating behavior or not. I took some pictures that I will post links to later, I managed to capture her belly and the color. If she is sick, is there a way of telling what exactly she is sick with and a type of treatment? Thanks in advance for all your help.

hummm lets start with the basics.... what are your water parameters, temp, nitrate, nitrite, ammonia, sg, ph ......... the usual......
next what are you feeding your fish and how much?
next how many clowns do you have??? Do you have a mated pair?
How is your bellied clownfish behaving? eratic? normal?

IMO.... pregnant fish...........
p.s is it a percula?

PREGNANT
She has a gut full of eggs by the sound of it.
Clowns lay eggs every 12-18 days, generally at the base of an anemone.
But if there is no anemone they will do it some where close to were they sleep.
The female, the larger of the two, will lay eggs, then the male will fertilize the eggs straight after.
Some times blowing on them with there mouth or fins.
This process will take around two hours.
If you look close there should be a real small white tube coming out around near their buts, just before they lay and fertilize.
The eggs will be protected by the clowns and anything coming close will be shewed away.
The eggs should be a orange color if the clowns are healthy.
They will eventually turn to a silvery color, and you will be able to see there eyes in their sacks.
Around this time is when they will hatch, a couple hours after lights out.
Then they will get eaten unfortunately, unless you get the out just before hatching, or immediately just after
You must read up on raring clowns, they require rotifers to eat and lots of them.
And have to be in a seperate area so nothing eats them.

Read this to help you more, as my knowledge is only limited.
