What to do with pregnant goldfish(fantail)?
You dont have to do anything. Goldfish dont really get “pregnant” though. The females can become full of eggs but they dont get fertilized until she releases them and the male will release his milt. If you dont have a male then you dont have to worry about babies but the female can still lay them without a male. Oh and goldfish do breed in captivity. I won 3 from a fair 2 years ago and they have breed twice so far and I am far from a pro even though I have been raising goldfish since I was little. I’m only 23 btw.
