Microalgea (Eg. spirulina)
Macroalgea (Eg. seaweed / nori)
This species is very sensitive during transportation and acclimatizing into the aquarium.
This species can eat large amounts of algae (relative to their size) from rocks, like green hair algae and filamentous algae.
As it doesn’t eat every algae type, in case of a specific algae plague, find out more precise information.
Sea hares are very effective at eating most types of algae, although not all of them, so do research this beforehand.
As opposed to Nudibranches they have an internal shell for protection. Furthermore, they will release a kind of ink when feeling threatened. This is not poisonous, but should be removed by changing the water.
Sea hares require a great deal of algae to survive, so it is advisable to pass it on when its task is accomplished.
When it dies, a large amout of nutients are released to the water, so it must not be kept too long without sufficient algae.
Most species are easy to keep in an aquarium as long as there are enough algae, although some species do have slightly more specific food requirements.

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
