Is it bad if angelfish eggs are fuzzy looking?

Fuzzy-looking angelfish eggs are a bad sign. This usually indicates that the eggs have been infected with a fungus.

Here's why this is a problem:

* Fungus can kill the eggs: The fungus will consume the eggs, preventing them from hatching.

* Fungus can spread: If left untreated, the fungus can spread to other eggs or even to the parent fish.

What to do if you see fuzzy eggs:

1. Identify the fungus: Examine the eggs closely. If they have a white, fuzzy coating, it's likely a fungal infection.

2. Isolate the eggs: If possible, remove the infected eggs from the tank. This helps prevent the fungus from spreading.

3. Treat with a fungicide: Use a commercially available aquarium fungicide to treat the infected eggs or the entire tank. Follow the manufacturer's instructions carefully.

4. Maintain good water quality: This helps prevent future fungal infections. Ensure the water is properly filtered, aerated, and has the correct temperature.

Important note: Angelfish eggs can sometimes appear fuzzy due to mildew, which is a harmless type of mold. If you're unsure about the cause, consult with an experienced fish keeper or veterinarian.
