I was wondering, what two fish do you need to breed to get a golden goldbulb? Or does the GG come with the common egg sets?

You can't get any of the Goldbulbs from common eggs. Only fish that thrive in a level 1 Fish Environment come from those eggs. There are many combinations that will produce the Golden Goldbulb. Most people just check the Clever Arts database, or one of the spreadsheets that have been posted on the forums, when they want to look up fish combinations.

Wow, thanks for the info! But when you go to the clever arts database, can you use a fish one of one line and a fish two of another? Thanks again.

You can either put any two fish that you're interested in breeding (on the left side) to find out what they would produce, or you can put in a desired fish (on the right side) and the database will list all of the combinations that will produce that fish.

Well if you put the fish desired I mean on the right side and then the combinations come up, could you then say,
Fish 1:Fish name Fish 2:Fish name <Use this fish
Fish 1:Fish name <And use this fish? Fish 2: Fish name

And then come out with the desired fish?

Each line in the list is independent of the other lines and contains one combination that will produce the desired fish. Fish 1 + Fish 2 = the fish that you want to make (the one that you put in on the right side under Fish Wanted).

Alright thanks again!
