Tropical Fish secondary texture is always white

Whenever you spawn a tropical fish, in any way, part of the fish is white. It’s blue and white, orange and white, red and white, green and white. It’s always some color with white. They aren’t colorful anymore, I don’t know if this is a new feature or something, but it’s been bothering me for a while. I’ve searched for this and each time I do it says it’s resolved, but I can’t figure it out, it still won’t work.
