Sick Yellow Boxfish..

[Maverick00]

I picked this guy up about 4 weeks ago. Seemed to be doing great but i noticed a problem this morning. Its right side fin looked enlarged and isnt moving, the top right side of its head appears to be bleaching from the fin outward. Feed cycle is brine shrimp every other day and it did eat this morning with no issues. Whats the best steps to address this matter? Should I Quarantine? FYI its a baby, size of a dime.Thanks for the help..

Brine is junk. Like a bag of chips... Little nutritional value.

Use mysis. I doubt that's the issue though.

Check water parameters and post.

I tried feeding mysis but the boxfish didnt seem interested, perhaps the pieces were too big? I did feed this morning with brine and it was eating.

i fed alittle more brine shrimp and it ate alittle more. the top of its head is slowy turning from a bleached white to a darker grey color... :\ i hope this guy pulls through

UPDATE

The color on the boxfish has gotten better. Its head was near black a week and a half ago. Its slowly getting its full color back and looks great. Not sure what happened here but im glad its bounced back :)
