Hello Maahir,  Most Aquarists have a bachelor's degree in marine biology, zoology, or other related field at minimum. Students looking to have an edge in the job market should pursue internships at local aquariums. Because the majority of the workday involves being around and in water, everyone pursuing this field must hold a scuba diving certification, as well as certifications in CPR. Advancement in the field typically depends on work experience.

Hope it is helpful for  you :)
