My Minnow Is In Love With My Goldie

Brief background: minnow spent several months alone with the goldie; immediately after adding two fantails, the minnow nosed and pushed goldie away from the fantails in a protective, possessive manner; ergo, we figured minnow is male and goldie female. The minnow has calmed down somewhat, but at feeding time, he is hyper, swimming erratically (excitedly?) as the three goldies feed. Minnow quickly snags some food from the surface, but continues the erratic behavior so long as the goldies are feeding. Two questions really: What do you make of this behavior, and can a minnow fertilize goldfish eggs.

actually, since the minnow is a cyprinid, the answer is surprisingly yes: it can fertilize goldfish eggs. The offspring will likely be sterile hybrids if they survive, however.

Wild goldfish colonies in the remote parts of Eurasia have been observed to be composed entirely of female fish. They reproduce themselves by joining in the group-spawning activities of other cyprinids in the area. Apparently their eggs contain the necessary genetic material to clone themselves over and over for generations, needing only the sperm of other fish to trigger the zygote to start cellular division. The Amazonian Livebearer also uses the same reproductive strategy.
