Hi Mojang,
I have discovered a bug on the Java Edition of Minecraft that affects the snapshots, pre-releases and upcoming release of 1.13. When a tropical fish gets picked up by a water bucket, and then you use that water bucket- the fish that comes out isn't the same colour as the one that went in. E.g. if I picked up a blue fish into the bucket, a orange one might come out (or a different colour/pattern). I hope you fix this. Thank you very much.

Yours sincerely,
Basil (SoupChildREVAMPED)
