Koko ja ulkonäkö |


Juovavälskäri kasvaa 35–40 cm pitkäksi. Sen vartalo on vaakasuuntaan kelta-siniraitainen, vatsapuoli vaalean liila ja vatsaevä keltainen.[2]



Alkuperä |


Juovavälskäreitä elää koralliriutoilla Indopasifisella merialueella. Ne viihtyvät riutan reunamilla, missä veden liike on voimakasta ja happipitoisuus suuri.[3]



Käyttäytyminen ja lisääntyminen |


Juovavälskäri on reviirikala. Suurikokoinen koiras vartioi laajaa, hyvin määriteltyä ruokailureviiriä ja naaraiden haaremia. Nuoret yksilöt elävät yksin ja piilottelevat matalassa vedessä kivikon keskellä.[4]


Akvaariossa juovavälskäri on hyvin aggressiivinen lajitovereitaan ja muita välskäreitä kohtaan. Se tarvitsee paljon uintitilaa.[5]


Juovavälskärit kutevat ryhminä.[6]



Ravinto |


Juovavälskärit syövät pääasiassa kasvisravintoa, mutta nieleskelevät sen ohessa myös pieniä äyriäisiä.[4] Akvaariossa ne syövät etenkin akvaariossa kasvavaa levää mutta myös kuivaruokaa.
