I have a 55 gallon that I’m starting I already see coral that I would want in my tank the guy at the fish store says some coral need special lighting and showed me a 600 dollar light but when I read forums or google it makes it seem as I don’t need that expensive light right away I can go with a normal light so my question is will any marine light do for all coral or do I need to go that expensive if I need to I will but if not I won’t
