Reaching around 18 cm, it drifts and creeps over rock and sand in search of tiny prey. This is a specialist fish that rewards patience, a mature aquarium and a dedicated keeper.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eCorythoichthys intestinalis is found across the tropical Indo-Pacific, on shallow coral reefs, rubble slopes and quiet lagoon floors. It spends its days working slowly over the substrate and live rock, picking at the film of tiny crustaceans that live there. In the aquarium it does best in a settled reef or dedicated species tank with plenty of mature live rock, gentle water movement and abundant microfauna. A newly established tank rarely provides the constant supply of small live foods this fish depends on.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThe body is long, thin and pale, overlaid with intricate reddish to brown lines and speckles that give the \"scribbled\" name. The snout is tubular and the mouth tiny, suited to sipping minuscule prey. Movement is graceful and deliberate rather than fast. Healthy specimens are alert, feeding steadily and free of pinched bellies, cloudy eyes or lesions.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eThis is a thoroughly peaceful, timid fish that will not compete with boisterous or fast-moving tank mates. It is easily out-competed at feeding time and can be stressed by aggressive fish. It is best kept in a calm reef or species tank with equally gentle companions such as small gobies, seahorses or other pipefish. Multiple pipefish can be kept together in a large, food-rich system.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eFeeding is the main challenge with this species and the reason it is considered expert-only. The tiny mouth requires very small foods: live copepods, baby brine shrimp, rotifers and amphipods are ideal. Some individuals can be weaned onto enriched frozen mysis or cyclops, but many will only take live foods, so a reliable pod culture or a heavily seeded refugium is a great help. Feed small amounts several times a day.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eProvide a minimum of 75 L, with 100 L or more recommended, ideally as a mature reef or dedicated species aquarium. Maintain 24–27°C, pH 8.1–8.4 and salinity around 1.020–1.026. Keep water movement gentle so the fish is not blown about, and guard intakes so it cannot be drawn against them. Stable, pristine water and a rich population of live foods are the keys to success.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eLike other pipefish, males brood the eggs, carrying them on the underside of the body until the young are released. Breeding has been achieved in dedicated setups but rearing the tiny fry requires a continuous supply of appropriately sized live foods and is beyond most home aquariums.

Reaching around 10 cm, it is famous in the hobby for one very useful trick: a genuine appetite for pest Aiptasia anemones, which it picks off the rocks. It is a fascinating, characterful fish for a peaceful system, though reef keepers should be aware it may also sample corals, so it is best considered reef safe with caution.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eAcreichthys tomentosus is found across the Indo-Pacific in shallow lagoons, seagrass beds and coastal reefs, often over weedy or algae-covered substrate where its camouflage helps it disappear. It is a slow, deliberate swimmer that drifts among cover, picking at small invertebrates, algae and anemones. In the aquarium it does best in a mature, peaceful tank with plenty of live rock, some algae growth and quiet corners to explore and shelter in.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThis filefish has a laterally compressed, leaf-shaped body in variable shades of green, brown and cream that it can adjust to match its surroundings, often with fine mottling and small skin filaments (the \"bristles\" of its common name) that enhance the camouflage. The first dorsal spine can be raised like a small flag. Healthy specimens are alert, hold good body condition and actively pick over the rockwork; avoid thin fish with pinched bellies, as filefish that have stopped feeding are hard to recover.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eTemperament is peaceful and rather shy. The Green Filefish is not aggressive and mixes well with other calm, non-boisterous fish, but it can be nervous and outcompeted at feeding time by pushier species. It should not be kept with small ornamental shrimp, which it may pick at, and it should be watched around prized corals.

It is an omnivore that will graze Aiptasia, small invertebrates and algae, and it usually accepts a range of aquarium foods including enriched mysis, vitamin-soaked brine shrimp, finely chopped meaty foods, marine pellets and some algae-based preparations. Feed two to three times a day. Do not rely on Aiptasia as its only food source, as a supply of pest anemones will not sustain it long term.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eProvide a minimum aquarium of around 110 L.

The pointed, upturned snout, the filamentous extension on the tail and the prominent belly flap are the easiest identifying features. Males and females can differ in fin and dewlap development.

Unusually, it is euryhaline, tolerating marine, brackish and even fresh water, and in aquaria it often does best in weakly brackish conditions. Replicating this environment means providing calm water, fine substrate, seagrass or macroalgae and plenty of gentle hiding structure. A mature, stable, low-flow system with an established population of small live foods suits it best.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThe Beady Pipefish has the long, thin, segmented body and small tubular snout typical of pipefish, with a subtle mottled pattern that gives good camouflage among plants. It reaches around 16–18 cm. Its slow, deliberate movement and delicate feeding are part of its appeal. Healthy specimens are alert, feeding steadily and well-filled along the body, without a sunken or pinched appearance, which in pipefish is a common early sign of a fish that is not eating enough.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eTemperament is best described as peaceful and delicate. It is easily outcompeted for food and stressed by boisterous tank mates. Suitable companions are other slow, gentle fish such as small gobies, dragonets and seahorses in a dedicated system. Avoid fast, greedy feeders, aggressive fish, and anything large enough to harass or eat it.

Offer frequent small feeds of enriched live and frozen foods such as baby brine shrimp, live and frozen Artemia, copepods and small mysis. Many individuals need live foods to begin feeding and only later accept frozen. A mature tank with a self-sustaining population of copepods and amphipods greatly improves success. Feed several times a day and watch body condition closely, as pipefish decline quickly if underfed.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eFor long-term success, provide a minimum aquarium size of 100 L for a dedicated pipefish system, with a larger, mature tank preferred for stable live-food populations. If kept brackish, a specific gravity around 1.005–1.010 is often used; in a marine system aim for around 1.020–1.026. Maintain temperature at 24–26°C and pH 8.0–8.4. Keep flow gentle, provide fine substrate, seagrass or macroalgae and abundant calm shelter. Use gentle filtration with protected intakes and carry out regular small water changes.
