Some species produce adhesive eggs to help them stick in place. This method of reproduction helps ensure the survival of the eggs. Fish reproductive methods vary … Read more

Many fish avoid sea anemones because their stinging tentacles can harm prey. Not all fish die from them, but some, like clownfish, form a symbiotic relationship for safety. Yet, fish that get too close face risks, including being stung or killed, impacting their survival in the marine ecosystem. However, not all fish are so fortunate. … Read more

Gambusia affinis, or mosquito fish, contribute to mosquito control by eating mosquito larvae. They consume these larvae after the eggs hatch. While mosquito fish do not eat mosquito eggs directly, their diet includes different insects and plant matter. This feeding habit helps maintain a balanced ecosystem and lowers mosquito populations. Incorporating these fish into your … Read more

Most fish eat their eggs and fry, especially in planted tanks. Territorial males guard nests while sneaker males quietly fertilize eggs, which can lead to more parental cannibalism. To protect fry, remove them after spawning. Eggs are nutritious but should only be a treat in a balanced diet. This dynamic influences egg survival. If larger … Read more
