Is my fish pregnant? Fantail and black moor Fish

TreeFrog32

I got two Goldfish about a month ago and the orange fantail had trouble swimming so I assumed she had swimmer bladder and my black moor had some white spots so I assumed he has ich or something. I decreased their diet and now the fantail swims better

Egg laying fish do not become pregnant, they are gravid or full of eggs. Fertilization occurs outside of the body once eggs are laid, no pregnancy like livebearers would have. So no your goldie is not pregnant. Being gravid is a common occurrence in fish but that dose not mean they will/should breed. Usually eggs are either expelled or reabsorbed if they do not spawn.

As for the black one, breeding stars will develop on the gill plates, pectoral and sometimes analfins of most carp species. The picture of the moor is pretty blurry and I can’t really tell if it has the stars. Do not treat for anything yet, throwing meds in without being sure if they are needed will cause more harm than good.

When it comes to ick I don’t use meds at all but rather the heat treatment and lots of water changes, maybe a bit of salt if there are no sensitive critters in the tank. First make sure they have ick, which appears and slat grain all over the body but most often on their fins. There is no pattern to where the spots appear, breeding stars will be pretty symmetrical on either side of the fish. If your moor only has them on the gill plates (cheeks) and the bony edge of his pectoral fins then they are certainly the stars.

Hi sorry the black moor moves a lot it's hard to take a picture but here are some better ones. Thank you for your reply. So is my fantail full of eggs?

Yup those looks like stars to me. As for the fantail, I do not know if it’s full of eggs or not. Some fancy goldfish are bred to be extra pudgy so it’s hard to tell. Normally the vent area will protrude a bit more than usual if a female is ready to spawn.

For the finer details on goldfish spawning, I would start googling and researching all you’ll need to know.

Thanks so much! I see the black moor pushing the fantail a lot too.
