The baby goldfish are now 9 days old. As you can see, some of them have plumped up quite a bit with round little white bellies.
Some personalities or individual characteristics have also started to become visible.
For instance, the largest and strongest fish tend to stay at the top section of the water. They get first pick of the egg yolk that I feed them, eating big gulps of it at a time. As the yolk starts to settle downwards, they follow it down, but tend to still stay towards the top section.
A few of the babies lurk among the plants. They tend to be less visible and they tend to pick at the plants or pick egg yolk off the plants to eat.
On the ground level, you will find the smallest fish. When one of the bigger fish swim down to the bottom to pick up food, you might notice that the ground-dwellers are almost half the size and much skinnier.
The ground level is also where you will find some fish with birth defects. For instance, this particular fish shown above has a spine that is curved in a spiral fashion. As a result, this fish will actually spin as it swims upwards in a jerky manner. This fish is not very strong and tends to swim in short spurts and not very far. Most of the time, it lies on the gravel. It is one of my favourite fish to look for and watch. I hope it survives.
There is one fish with a back that is bent less and it is able to swim to the top in a much wider spiral to get food. It is still much skinnier than the others, but it is clearly much stronger than this one since it can swim all the way to the top.
Even at the top, there are a few fish that seem unusual. There is one fish at the top that is very long, but very thin. It tends to just float at the top of the water, not really eating. I am not sure if it is sick, if it doesn't store food in the intestines much, or if it eats very little at a time.
It is fun to watch these little fish growing up. I am still giving them both the green water and the drop of egg yolk 2-3 times per day. They don't react much to the green water, but I can visibly watch them eat the egg yolk. I use a wooden chopstick to just poke at a raw egg yolk that I have stored in the refrigerator. Then I stir the chopstick gently in the water and the egg yolk comes off in tiny slivers. I can watch the fry chase the slivers of egg and sort of suck it up as they eat at it. It's pretty neat.
Have a great day!
