I am a high school student who started this hobby about a year ago vigorously consuming the vast amount of knowledge this hobby contains. I am looking to increase my career through entrepreneurship as a source of income since I am very passionate about marine life and aquariums, so I was wandering if there are any problems you (The consumers) have or may faced in all your years of experience in reef keeping. Any tips at all would be greatly appreciated since I am new and serious about creating a small business.
