Anyone had experience with a cowfish?

I had a cowfish before and yes it was too small that it got suck to the powerhead, it was my bad of me. If it get too stress it could die. When it died all of my fish and inverts started acting weird they seem suffocated. I did 75% water change two days and they all survived....I guess it depends on how big of a cowfish you'll be adding.
