Tropical Fish unique color listing uses semicolons instead of commas when starting with Pink or Black.

Normally when you catch a colored tropical fish with a bucket, it will list the colors as “Fish - color, color.” but if the tropical fish’s listed colors starts with black or pink, it’ll be “Fish - color; color”

this is so incredibly niche that the only thing in my mind is that its an unnoticed inconsistency when they were adding the ability for fish to be random colors. However it is seemingly a bug. The attached images show the unusual semicolons and the usual comma that it tends to be. (i havent collected enough fish to notice if its more than these 2 colors.)
