DIY How to Hatch Angelfish Eggs


Normally, freshwater angelfish will take care and defend its eggs against other fishes. Angelfish eggs are patiently being fanned by the parents to keep off fungus. Sometimes you need to separate the eggs because, for some reason, the parents will eat them. Possible cause is they think the eggs aren’t healthy enough for them to survive so they eat them, especially if there is a threat.

Helping the angelfish eggs survive

You will be needing the following:

  • A separate grow-out tank
  • Slate
  • Air pump
  • Sponge filter


Angelfishes mate every week. Angelfish usually lays eggs on hard surface near above the water. If you put a slate in the tank which you can see from the picture above which is green in color, most probably they will stick their eggs on there on the upper portion. It is much easier to transfer the slate containing angelfish eggs into a grow-out tank.

If in case you opt to separate the newly spawned eggs into a separate tank, it’s better to put the aerator near the eggs to prevent having white eggs which are bad.  Few bubbles running on them will aid to deter fungus touching the eggs.

The baby tank must not have substrate to prevent existence of fungus.  Wait 3 to four days and the angelfish eggs will hatch. During the process you will first see the black eyes, then they’ll become wrigglers,  later on they become free swimmers.

You will be amazed that they will start going all over the place. The aquarium needs partial daily water change. Once the babies used up their yolk sac, they will hunt for food and hard-boiled egg yolk is one of the best food for them.

Baby brine shrimp will also do. They love eating them. The small angelfishes will start showing their color after 10 days. They look cute with their big eyes.

The babies must be fed several times a day but be watchful of the amount because uneaten food will foul the water and the toxin (ammonia) will kill your fishes.

Optimum tank parameters:

  • Temperature of 75-84 °F or 23-27 °C.
  • Slightly soft water (5 and 18 dH)
  • Slightly acidic water (between 6.0 and 7.5 pH)
  • Densely planted tank

Spots where angelfish spawns and lays eggs:

  • Broad leafed plant
  • Slate
  • Inverted pot
  • Elevated hard surfaces in the water
  • Water pump hose

Angelfishes are not fickle eaters

It is ideal to feed them various food to maintain good diet. They accepts:

  • Fish flakes
  • Algae wafers
  • Floating or sinking pellets
  • Spirulina pellet or flakes


Take note that live food can also be fed with angelfish but make sure they are not contaminated and are healthy. Here are some examples:

  • Brine shrimp
  • Daphnia
  • Worms: grindal, white, and micro
