What Do Different Types of Fish’s Eggs Look Like?
1. What Do Goldfish look like?
Goldfish eggs look like small bubbles with a transparent, whitish color. The whitish look will then turn yellow with a small dark spot in the middle after getting fertilized.
The eggs of goldfish are sticky. You can see a white patch attached to a leaf or decoration item after this fish lay eggs in aquarium.
Goldfish are well-known as prolific breeders that can lay hundreds to 1000 eggs at a time and multiple times a week in good condition.
However, goldfish are one of the fish species that don’t have parental instincts. They are notorious for eating their newly hatched eggs.
Therefore, to protect baby fish eggs, you should isolate the eggs to another tank or remove adult goldfish to prevent the fish from eating all the eggs.
2. What Do Angelfish Eggs Look Like?
When first laid, angelfish eggs are extremely small, just like white pearls. Some aquarists also said that fish eggs feel like “jelly”. After getting fertilized, the eggs will turn from translucent to slightly brown. But if you see the stark white eggs, it means they weren’t fertilized.
The fact is that a female angelfish can produce hundreds to a thousand eggs. Sometimes, angelfish also eat their eggs due to the lack of food or under major stress.
3. What Do Glofish eggs look like?
Just like regular fish eggs, Glofish eggs look like tiny balls. They have a stark white color initially first, then turn yellow fish eggs after getting fertilized.
The interesting thing about the Glofish is that their fertilized eggs will fall to the bottom of the tank. Meanwhile, unfertilized ones float above the water’s surface.
Glofish species also can produce hundreds of eggs but don’t have maternal instincts. Like goldfish, they will proceed to devour their baby eggs.
Therefore, you better transfer the parents for your fish’s safety once you see fish eggs in tank.
4. What Do Blood Parrot Eggs Look Like?
Blood parrot fish eggs in water appear a whitish color. After getting fertilized, these tiny Parrot fish eggs will turn clear or milky white with wavy membranes surrounding them. In contrast, infertile eggs will likely look smaller.

5. What Do Betta Eggs Look Like?

Betta fish will rarely eat their eggs unless they are starving and have no other choice. But most of the eggs they swallow are not typical; they may be unfertilized or fail to spawn.
6. What Do Corydoras Eggs Look Like?
Corydoras eggs are a transparent white color when first laid. Eggs will be laid in clusters of 10-20 eggs, each of them measuring about 1-2mm in size.
After fertilization, from one to two days, the egg’s color will turn from white to brownish with a small black spot.
On average, a female Corydoras can lay between 10 and 50 eggs at a time. Corydoras prefer laying eggs against aquarium glass; this feature sets them apart from the rest.
But just like the other Goldfish or Angelfish, Corydoras offers no parental care, they will eat their eggs. So it’s better to isolate the parents as soon as possible to protect the aquarium fish eggs.
