How long does a glo fish stay pregnant?

My mom's fish has been pregnant for about 4 months very soon and we think that's too long to be pregnant for. We are concerned about how long they are supposed to be pregnant for. Please help us!

it probably has dropsey because those fish lay eggs

if you are talking about the dyed danios or geneticly altered ones, probability are its not. They are egg layers so aren't what you would traditionaly consider as pregnant. I suppose it could have eggs in it, but whether theres a male in the tank it would own likely scattered them already if the conditions be ideal.

Answers:    They aren't genetically altered, there's no such entity they are injected with dye that's why countries who have good animal welfare annals have banned them, it is exceptionally cruel
They are zebra danios, they lay eggs and don't get pregnant at adjectives
