Hi, this is my first thread on Fish Lore! I have 8 mosquito fish(four males, four females) that I caught at a lake last summer. For all who don't know this, mosquito fish are an invasive species that is closely related to guppies. I began to chart their breeding on May 29, but they were most likely breeding before that. Today they only have the light pink spot, and they've been stuck in this phase for a while now. The average gestation period for a mosquito fish is 26 days... I just don't know why they aren't progressing at all. If anybody has an answer to this problem, that would be greatly appreciated! P.S. The females were in a tank with a turtle and the four males, but now they are in their own tanks. I know they can hold off on giving birth if they feel unsafe, but I thought it was later on in their pregnancy.
