Algae eater

Last updated

Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons. Algae eaters are important for the fishkeeping hobby and many are commonly kept by aquarium hobbyists to improve water quality. [1] They are also important primary consumers that relay the biomass and energy from photosynthetic autotrophes up into the food web, as well as protecting the aquatic ecosystem against algae blooms.

Fish

Some of the common and most popular freshwater aquarium algae eaters include:

Common freshwater algivorous fish:

Shrimp

Some freshwater shrimp are also excellent algae eaters:

Snails

Most species of freshwater snails, discounting most adult specimens of species belonging to the family Ampullariidae , which primarily subsist on aquatic plants as adults.

Saltwater

Some of the known types of fish to eat algae are blennies and tangs, but along with fish there are snails, crabs, and sea urchins who also eat algae. These species are known to eat red slime algae, green film algae, hair algae, diatoms, cyanobacteria, brown film algae, detritus, and microalgae. [3]

Fish

There are several saltwater fish species that eat algae. Two of the major algae eaters are blennies and tangs. These fish eat red slime algae, green film algae, and hair algae. Some of the known species are as follows:

Blennies: [4] [5]

Crabs

Hermit crabs and other species of crabs eat algae. Crabs eat green algae, film algae, red slime algae, diatoms, cyanobacteria, and microalgae. Some of the known species are:

Hermit Crabs:

Other Species: [7]

Sea urchins

All species of sea urchin eat algae. They eat all sizes of algae, from something as small as macroalgae to something as large as kelp, and have been known to eat Coralline algae. [8] In cooler waters, sea urchins have even been known to eat enough to control the size and compositions of kelp forests. Sea urchins act as scavengers and will also eat dead algae that they find. Some sea urchins, such as the variegated sea urchin or the red sea urchin, have become popular as pets for home aquariums because of their ability to proficiently eat algae. [9]

Snails

Snails are known for eating hair algae, cyanobacteria, diatoms, green film algae, brown film algae, and detritus. [10]

Reef safe is a distinction used in the saltwater aquarium hobby to indicate that a fish or invertebrate is safe to add to a reef aquarium. There is no fish that is completely reef safe. Every fish that is commonly listed as reef safe are species that usually do not readily consume small fish or invertebrates. Fish listed as reef safe also do not bother fellow fish unless in some cases, for instance tangs, they do not get along with conspecifics and sometimes fish with similar color or body shape. Every fish has a personality, is different, and, in some cases, are opportunistic feeders. Tangs, which by most accounts are reef safe, may in adulthood eat some crustaceans shortly after they molt. Many larger predatory fish, for instance eels and pufferfish, will adapt very well to a reef tank and will be problem-free as long as they have sizable tank-mates and no crustaceans. Some aquarists have also had success in keeping smaller fish with predatory ones in reef tanks by adding the smaller fish at night, sometimes with newly rearranged rockwork.

A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration.

The sohal surgeonfish or sohal tang, is an endemic from the Red Sea and Persian Gulf. A single record was reported in 2017 from the eastern Mediterranean Sea, a likely result of aquarium release. It can grow up to 16 in (40 cm) in the wild. It is a valued aquarium fish. Its striking blue and white horizontal stripes have made it for many the 'poster fish' for the Red Sea reef and Persian Gulf environment.

Paguristes cadenati, the red reef hermit crab or scarlet hermit crab, is a small species of hermit crab with a bright red body and yellow eyestalks that lives in the Caribbean Sea.

<i>Neocaridina davidi</i> Species of crustacean

Neocaridina davidi is a freshwater shrimp originating from eastern China and northern Taiwan and introduced in the rest of Taiwan, Japan, and Hawaii, which is commonly kept in aquaria. The natural coloration of the shrimp is green-brown. There are a wide range of colors including red, yellow, orange, green, blue, violet, black, etc.; however, the red morph is more frequently sold. The density of coloration on adult shrimp, dependent on breeding, determines their sale price and "quality" (grading). This "quality" is purely aesthetic, as the size, behavior and other characteristics of the animal are more or less equal across varieties. Full-grown shrimp reach about 4 centimetres (1.6 in) long. They prefer clean water, with a pH of 6.5-8, and a temperature of 14–29 °C (57–84 °F) They are most comfortable at 22 °C (72 °F). N. davidi shrimp are omnivores that may live 1–2 years. These shrimps have previously been classified as Neocaridina heteropoda and Neocaridina denticulata sinensis, however are now known as Neocaridina davidi which is based on the oldest known published description of the species.

<span class="mw-page-title-main">Bottom feeder</span> Aquatic animal that feeds on the bottom of a body of water

A bottom feeder is an aquatic animal that feeds on or near the bottom of a body of water. Biologists often use the terms benthos—particularly for invertebrates such as shellfish, crabs, crayfish, sea anemones, starfish, snails, bristleworms and sea cucumbers—and benthivore or benthivorous, for fish and invertebrates that feed on material from the bottom. However the term benthos includes all aquatic life that lives on or near the bottom, which means it also includes non-animals, such as plants and algae. Biologists also use specific terms that refer to bottom feeding fish, such as demersal fish, groundfish, benthic fish and benthopelagic fish. Examples of bottom feeding fish species groups are flatfish, eels, cod, haddock, bass, grouper, carp, bream (snapper) and some species of catfish, sharks.

<i>Gyrinocheilus aymonieri</i> Species of fish

Gyrinocheilus aymonieri is a freshwater fish native to large parts of Southeast Asia. It is of interest as a local food source and for the aquarium trade. Its common names include honey sucker, sucking loach and Chinese algae eater.

The clean-up crew is the term that has been used by many aquarists and vendors since the late 1980s to refer to various small animals commonly sold for use in keeping the reef aquarium clear of pest algae, detritus and parasites.

<i>Gyrinocheilus</i> Genus of fishes

Gyrinocheilus is the single genus in the family Gyrinocheilidae, a family of small Southeast Asian cypriniform fishes that live in fast-flowing freshwater mountain streams. The species in this genus are commonly called "algae eaters". They hold on to fixed objects using a sucker-like mouth, and, despite the name, feed on a wide range of detritus, rather than simply on algae. A "golden" variety of G. aymonieri, the Chinese algae eater or "sucking loach", can be found in many pet shops and fish farms.

<span class="mw-page-title-main">Feeder shrimp</span>

Feeder shrimp, ghost shrimp, glass shrimp, grass shrimp, river shrimp or feeder prawns are generic names applied to inexpensive small, typically with a length of 1 to 3 cm, semi-transparent crustaceans commonly sold and fed as live prey to larger more aggressive fishes kept in aquariums.
