The first and most obvious sign that your female fish is pregnant is that her belly will start to look swollen. The eggs cause this inside her body, and the presence of a fuller belly can make her look a lot larger than she actually is. But in reality, there is no official term for a goldfish because female goldfish do not get pregnant. Rather, female goldfish lay eggs and the eggs are fertilised by the men outside the body, so goldfish do not get pregnant, which in turn makes it impossible to name a pregnant goldfish. How long are goldfish pregnant for?

Some good sources of protein for a pregnant goldfish include live foods such as brine shrimp, daphnia, and bloodworms. Most healthy goldfish also do well on goldfish food that has been specifically formulated for pregnant fish. Typically, these foods are higher in protein than regular goldfish food.Oviparity: This is where the female’s eggs are fertilised internally but are then released into the water to develop. In excess of 97% of all known fish species are oviparous. Although fish eggs can vary in size, marine fish typically produce eggs that are a mere millimetre in size. Fish eggs do not develop a hard (or soft) shell yet are surrounded by an extra-embryonic membrane to aid development and provide protection. Newly hatched fish are called larvae and carry around with them a ‘yolk sac’ for nourishment. During the transition period from larvae to juvenile, the fish must learn how to feed on plankton (they lose their ‘yolk sac’ once they reach the juvenile stage of their development). Histotrophic or ’tissue eating’ viviparity: This is where embryos develop inside the mother’s oviducts yet receive nourishment from other tissues. For example, in some species of shark, the larger embryos will eat smaller embryos. It is important to note that while Urban Dictionary can provide insights into contemporary slang usage, it does not serve as an authoritative source for determining the historical or etymological origins of words. Conclusion Once goldfish fry hatch, they are extremely vulnerable to predators. As such, it is important to make sure that the spawning environment is free of any potential threats such as other fish, snails, or crabs. The best way to do this is to set up a separate breeding tank for your pregnant goldfish. This will ensure that her eggs and juvenile goldfish are safe and protected from potential predators.

Unlike livebearers such as guppies and mollies, goldfish do not give birth to live young. Instead, they lay eggs that hatch a few days later into fry. For the purposes of this article, a “pregnant” goldfish is simply a female goldfish that carries eggs inside her body. These eggs will eventually be released and fertilized by a male goldfish, at which point they will hatch into fry. Melissa Mohr suggests few Victorians knew the word, given that "none of the twenty-three or so Victorian editions" of Browning's poem omit it. [9] An 1868 query to Notes and Queries asked what the word in the poem meant; [12] the only published reply was, "Twat is good Somersetshire dialect for a toad=twoad=twat". [13] A footnote in William James Rolfe and Heloise Hersey's 1886 Select Poems of Robert Browning summarised his reply to Furnivall with the additional comment, " Twat is in no dictionary"; [14] H. W. Fay noted in 1888 in The Academy that the word was in fact in Thomas Wright's 1857 Dictionary of Obsolete and Provincial English, and said Browning, Furnivall and Rolfe had all made a "distressing blunder". [9] [7] [15] The 1894 reprint of Select Poems replaced the comment with "Browning would not have used the word if he had known its meaning". [16] In 1911 Basil Lanneau Gildersleeve alluded to "a notorious word which smirches the skirt of Pippa Passes". [17] Our version of the OED weighs maybe a hundred pounds. Obviously the goldfish guy was on drugs. We abandoned the pursuit of twat as, you should pardon the expression, a blind alley. Surprising as it may seem, one of the most crucial signs that your female fish is pregnant is if you see eggs falling out of her. This may happen when you touch her, or when she bumps into something in the tank. Brief Mention". The American Journal of Philology. 32 (2): 241. 1911. ISSN 0002-9475.

This is because her larger belly weighs her down in the water and she may look quite uncomfortable the next few days before depositing her eggs. If you have a filter that produces a strong current in the water, a heavily pregnant goldfish can get stressed trying to swim. If this is the case, adjusting the flow to a lower setting can make it easier for her. In fish, fertilisation of eggs can be either internal or external, with many species of fish having evolutionary fin adaptations to facilitate internal fertilisation. Similarity, the development of embryos can also occur internally or externally – with some fish species even switching partway through embryo development. In fact, there are actually five classifications of ‘reproductive strategies’ in relation to the development of the zygote and its (inter)relationship with its parents; these are as follows: Peter Silverton, Peter (2011).

It also is not on the list of the seven dirty words by George Carlin in his 1972 monologue "Seven Words You Can Never Say on Television", [42] perhaps because the word is much less common in North America than in Britain, although it was used as a term of insult in Mel Brooks' comedy western Blazing Saddles (1974). Male goldfish are ready to mate when they develop white spots on their gill covers, known asbreeding tubercles. These spawning tubercles are a sign that the male goldfish’s body is maturing and that he is ready to start reproducing.
