This species is not a true nudibranch, but it is often grouped with sea slugs in the hobby because of its similar invertebrate appeal. In the aquarium, it is best suited to established marine systems with plenty of natural algae growth and excellent water quality.\u003c\/p\u003e\u003cp\u003eSea hares are peaceful, slow-moving grazers that spend much of their time browsing on film algae, hair algae and other soft algal growths. They are not a permanent solution to an algae problem, but they can be a very useful part of a balanced clean-up crew in the right setup. Because they can be sensitive to poor water conditions and sudden changes, they are recommended for aquarists with some marine experience.\u003c\/p\u003e\u003cp\u003eAt Tropical Fish Co, we supply healthy marine livestock with a \u003cstrong\u003elive arrival guarantee\u003c\/strong\u003e and \u003cstrong\u003efast UK delivery\u003c\/strong\u003e, helping your new invertebrate arrive in the best possible condition.\u003c\/p\u003e\u003ch2\u003eCare at a Glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eCare Factor\u003c\/th\u003e\n\u003cth\u003eRecommendation\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003e\u003cem\u003eDolabella auricularia\u003c\/em\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eSea Hare\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCare Level\u003c\/td\u003e\n\u003ctd\u003eModerate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdult Size\u003c\/td\u003e\n\u003ctd\u003eUp to 15 cm, sometimes larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e50 litres minimum, larger is better\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature\u003c\/td\u003e\n\u003ctd\u003e22–26°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH\u003c\/td\u003e\n\u003ctd\u003e8.1–8.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eHerbivore; algae grazer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTank Region\u003c\/td\u003e\n\u003ctd\u003eBottom \/ rockwork \/ glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eOrigin \u0026amp; Natural Habitat\u003c\/h2\u003e\u003cp\u003e\u003cem\u003eDolabella auricularia\u003c\/em\u003e is found across tropical Indo-Pacific waters, where it inhabits shallow coastal areas, lagoons, seagrass beds and reef flats. In nature it lives among rocks, rubble and algae-rich surfaces, feeding on a wide range of benthic algae and organic growth. Its natural environment is warm, well-oxygenated and stable, with plenty of hiding places and abundant food sources.\u003c\/p\u003e\u003cp\u003eThis species is adapted to a life of grazing and camouflage rather than speed or defence. When threatened, sea hares may release a purple ink-like secretion as a deterrent. While this is a natural defence mechanism, it can stress aquarium livestock if the animal is injured or dies, so careful handling and close observation are important.\u003c\/p\u003e\u003ch2\u003eTank Setup \u0026amp; Water Parameters\u003c\/h2\u003e\u003cp\u003eFor best results, keep \u003cem\u003eDolabella auricularia\u003c\/em\u003e in a mature marine aquarium with stable salinity and excellent filtration. A tank of at least 50 litres may be suitable for a single specimen, but larger systems are strongly preferred because sea hares can produce a noticeable bioload and may run out of food in smaller aquariums. They do best in tanks with natural algae growth on rockwork and glass.\u003c\/p\u003e\u003cp\u003eProvide plenty of live rock, open grazing surfaces and gentle water movement. Avoid strong powerhead intakes, as sea hares can be slow and vulnerable to being trapped or injured. A secure lid is also sensible, as unusual invertebrates can sometimes end up in awkward places. Keep the system fully cycled and mature before introduction, and ensure that salinity, temperature and pH remain stable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRecommended parameters:\u003c\/strong\u003e temperature 22–26°C, pH 8.1–8.4, marine salinity 1.023–1.026 specific gravity. Ammonia and nitrite should always be zero, and nitrate should be kept as low as practical. Like many marine invertebrates, sea hares are sensitive to copper and other medications, so never place them in tanks that have been treated with copper-based products.\u003c\/p\u003e\u003cp\u003eBecause this species can be sensitive to sudden changes, acclimation should be slow and careful. Drip acclimation is usually the safest approach, especially if the salinity in the holding system differs from your display tank.\u003c\/p\u003e\u003ch2\u003eFeeding Guide\u003c\/h2\u003e\u003cp\u003e\u003cem\u003eDolabella auricularia\u003c\/em\u003e is primarily herbivorous and feeds on algae. In established aquariums it will graze on film algae, green hair algae and other soft algal growths. However, it should not be relied upon as the sole food source unless the tank naturally produces enough algae to sustain it. In cleaner systems, supplemental feeding may be required.\u003c\/p\u003e\u003cp\u003eOffer suitable marine algae foods such as dried seaweed sheets, blanched leafy greens in moderation, or specialised herbivore foods designed for marine grazers. Feed small amounts regularly and observe the animal’s activity and body condition. A healthy sea hare should appear full-bodied and active, with regular grazing behaviour. If it becomes inactive or begins to shrink noticeably, the tank may not be providing enough food.\u003c\/p\u003e\u003cp\u003eDo not feed meaty foods as a routine diet. These animals are adapted to plant-based grazing and may not thrive on unsuitable foods. As with all marine invertebrates, avoid overfeeding the tank, as excess waste can quickly degrade water quality.\u003c\/p\u003e\u003ch2\u003eTank Mates \/ Compatibility\u003c\/h2\u003e\u003cp\u003eSea hares are peaceful and generally compatible with calm community marine fish and non-aggressive invertebrates. Good tank mates include clownfish, gobies, blennies, cardinalfish, tangs, cleaner shrimp and other gentle reef-safe species, provided the aquarium is large enough and well established. They are best kept with fish that will not nip at soft-bodied invertebrates.\u003c\/p\u003e\u003cp\u003eAvoid keeping them with aggressive or highly inquisitive fish such as triggers, puffers, large wrasses, dottybacks and some butterflyfish, as these may harass or injure the sea hare. Crabs, large hermit crabs and predatory shrimp can also be problematic. It is also wise to avoid housing them with species known to nip at soft-bodied molluscs.\u003c\/p\u003e\u003cp\u003eAlthough \u003cem\u003eDolabella auricularia\u003c\/em\u003e is generally reef-safe in the sense that it does not prey on corals, it may occasionally be knocked about by strong flow or disturbed by active tank inhabitants. Because it can release defensive ink if stressed, it is best kept in a calm, stable aquarium where it can graze undisturbed.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Tropical Fish Co\u003c\/h2\u003e\u003cp\u003eWhen you buy marine livestock from Tropical Fish Co, you get more than just a beautiful animal for your aquarium.
