Not exactly sure what version it is but I think it is my current Nintendo switch version which auto updates but I was just in my creative world and I placed my tropical fish that I collected. They all turned white when they were placed. The clownfish weren't even clownfish anymore which was also very odd. I saw it before placing my fish in the glass case  but thought they were just fish passing by. Please fix the bug! It is when I place tropical fish, they turn into white versions.
