The bluestreak cleaner wrasse (Labroides dimidiatus) is a tiny, blue, black, and white fish native to the Indo-Pacific's coral reefs. They are known for establishing "cleaning stations" on reefs, where larger fish visit to have parasites and dead skin removed. This symbiotic relationship, called mutualism, benefits both the wrasse and the fish it cleans. Habitat: coral reefs Species: L. dimidiatus This fish is very peaceful and gets along with other peaceful tank mates. They will even be tolerated by more aggressive fish, as they are recognized as parasite cleaners. Even cleaner wrathes that have been fully transitioned onto prepared foods will clean their tankmates. wrathes can live for several years, even up to 10 years in some cases. Cleaner wrathes clean larger fish by eating parasites, dead tissue, and sometimes even food particles off their bodies. performing a dance-like motion in which they move their rear up and down. The visitors are referred to as "clients." Bluestreak cleaner wrasses clean to consume ectoparasites on client fish for food.

Damselfish are a diverse group of colorful, small reef fish, often seen in aquariums and known for their territorial and sometimes aggressive nature. They are popular among aquarium hobbyists due to their hardiness and vibrant colors. Key Characteristics: Diversity: The Pomacentridae family, which includes damselfish, comprises over 330 species. Territoriality: Damselfish are known for being territorial and can be aggressive, especially when defending their territory or home. Diet: Their diet varies depending on the species, with some feeding on algae, plankton, and even small invertebrates. Aggression: Due to their territorial nature, some damselfish species can be aggressive. Many species live in tropical rocky or coral reefs, and many of those are kept as marine aquarium pets. Their diets include small crustaceans, plankton, and algae. However, a few live in fresh and brackish waters, such as the freshwater damselfish, or in warm subtropical climates, such as the large orange Garibaldi, which inhabits the coast of southern California and the Pacific Mexican coast.

Wasps are winged insects with slender bodies, narrow waists, and well-developed wings. They are part of the Hymenoptera order, which also includes ants, bees, and sawflies. Wasps are distinguished from bees by their pointed lower abdomen and smooth bodies with few hairs. Wasps are mostly carnivorous and can be solitary or social. Solitary wasps are selective in their prey, often focusing on a single genus or order. Wasps belong to the Hymenoptera order and the Apocrita suborder, but they are not a single, unified clade; instead, they are a paraphyletic group within Apocrita that excludes ants and bees. The scientific name for wasps, broadly defined, is Hymenoptera. Wasps are generally repelled by strong scents, particularly those found in certain plants and essential oils. Some of the most effective deterrents include lemongrass, peppermint, marigolds, and citrus fruits Wasps have several weaknesses, including being attracted to sweet foods, sensitive to certain smells like peppermint oil, and vulnerable to being drowned in a solution of water and dish soap. wasps serve a valuable purpose in ecosystems by acting as both predators and pollinators, contributing to natural pest control and plant reproduction. We now know that when injured or killed, a wasp releases pheromones that alert other wasps of a threat. This is why other wasps seem to swarm around and seek revenge when you kill a wasp. Wasps can become especially aggressive when their nest is disturbed. certain species of wasps, like paper wasps, can remember faces, including other wasps and even humans. This ability is likely linked to their social structure and the need to recognize individuals within their colonies. If wasps feel threatened or if their nest is disturbed, it makes them very aggressive and provokes them to sting. If you see a wasp nest, follow the tips below: Do not approach a wasp's nest during the day when they are the most active. Wasps can sting multiple times.
