Spawning takes place, the eggs take four days to hatch, and three days later the fry are free swimming.ДЄt hatching the fry are 3/16' (4.5mm) in length.ДЄt free swimming stage the fry are 7/32' (5mm) in body length. Weekly Growth and Development Milestones Week One (day 1 to 7) If fry are fed three times daily, or provided with live food continuously, the growth rates shown can be exceeded. The fry have been fed twice daily with enough live food to last an hour. The growth rates shown in the chart are for Black Moor fry kept at a water temperature of 75 oF (24 oC) for hatching, and between 68-77 oF (20-25 oC) from the second week onwards.Д«lack Moor fry growth rate first eight weeks To increase its length by 25%, a slim bodied variety has to double its body weight, so for a deep bodied variety to increase its length by 25%, the figure is closer to triple. Their body weight gain will be the same, but their body shape is deepening at the expense of overall length. I have used one of my spawns of Black Moor as an example of deep bodied goldfish growth rates, as most growth charts are for slim bodied varieties.ДЄll goldfish fry have the same physical characteristics for the first 5 weeks, so the growth rate is similar for all varieties up to that age.ДЄfter 5 weeks the deep bodied varieties start to take their adult shape, so growth rates slow when compared to the slim bodied varieties such as Comets. Goldfish Growth Rates For The First Eight Weeks If the flukes don't kill the fry, they severely retard growth. Fish under two inches (52mm) in body length are susceptible to parasites such as gyrodactylus (body flukes) and dactylogyrus (gill flukes).

Once your Goldfish have spawned, learn how to successfully raise your fry. Some high quality prepared foods can be supplemented at around week 5, but most fancy varieties need live food to make up the majority of their diet for around 6 months. Most hobbyists don't provide enough food for fry to grow at their maximum rate, which is critical for the first month.ДЇry need to be fed live food for the protein. I don't doubt this claim gauging from the amount of food my fry go through in a day. It has been claimed fry will eat their own body-weight of food a day if enough is provided. Some breeders keep metallic scaled fish at 80 oF (26.7 oC) for the first month to accelerate the color change. Temperatures around 75 oF (24 oC) can be used for hatching the eggs and maintained for as long as maximum growth rates are required. The water temperature for fry and younger fish can be higher than for adults. Goldfish need high oxygen levels to enable them to process the large amounts of food needed to grow quickly. Goldfish need 24 square inches of surface area per inch of fish, or a filtration/aeration system. What actually happens is the build up of growth inhibiting hormones stop the fish, and any other Goldfish in the same container, from growing any bigger. This is why there is the widely held belief that Goldfish only grow to the size of their container.

This is especially important for fry when large numbers are often kept in crowded conditions for the first few weeks.ДЄnother equally important reason for water changes is Goldfish produce hormones that inhibit growth. Goldfish can tolerate many different water conditions, hard, soft, acid or alkaline, but they won't tolerate water with ammonia in it or low oxygen levels caused by pollution.ДЇrequent water changes are required for goldfish. Goldfish kept in a crowded aquarium or bowl and only fed dry prepared foods will not thrive.ДЇive factors determine how fast a goldfish grows: 1. Goldfish growth rates are totally dependent on the conditions they are kept in, and the amount of high quality food they receive. Goldfish growth rates can be massive for their first few weeks after hatching in a perfect growing environment, as much as a 50% or more increase in body length in a week.

Goldfish will not thrive in a crowded aquarium.
