You may fail to see the fry at first, as they are tiny and tend to hide in the gravel, but don't worry. They'll feed off organisms in the sponge filter and gravel for the first day or two. Pulling the eggs is rarely necessary as female apistos are fantastic mothers and almost never eat a viable spawn. They can however be a bit overprotective and can kill a mate if enough hiding places are not provided. Fry will accept baby brine shrimp, microworms, vinegar eels, or finely crushed flakes as first foods.
Live foods are best, and freshly-hatched baby brine shrimp are ideal for both fry and adults.
Given clean, soft, acidic water and nutritious foods, apisto fry should grow at a steady rate. Keep the water quality high. Here again is where I keep away from using too small of an aquarium. The presence of uneaten baby brine can foul the water quickly, so a small aquarium will need diligent maintenance while the larger tank is more forgiving. When ordering apistos, never order only a single pair.
