Hi could sonme-one please tell me how to breed, a pink beta? and also why when i breed a pink shark and a speckled leaf fish, intead of making a oriental goldbulb it makes a oriental firearrow

There are some very good breeding references in the Spoilers thread of the Fish Tycoon Guide.

I'm not sure what breeding reference you're using, but that combination has always produced the Oriental Fire-Arrow. If it's a breeding reference that's contained on this site, please let me know and I'll have it corrected.

To find out how to breed a pink beta, download "Fish Tycoon Fish Tool" from http://www.dreymire.com/Vid_Guides/Fish_Tycoon/fish_tycoon_breeding_guide.htm
Also, I think you can make an oriental goldbulb from a pink goldshark and a speckled leaffish... Perhaps you got the goldshark and shark confused?
