Welcome to the forums. I use Imgur for photos. To your main question, that will depend on the type of shrimp you hope to get. Have you looked into varieties and do any in particular catch your eye? The two big ones* are Caridina/often called crystals or bees (softwater) and Neocaridina/ often called cherries (most any water). Both breed like cockroaches when conditions are right, Caridina in my experience are far more sensitive and difficult. Both have reds, blues, blacks, and more available, Caridina are the only ones with substantial white pigment. For a first shrimp to get familiar with keeping them, I would recommend Neos hands down. With either, they feed upon algae and biofilm largely. You barely even need to feed these creatures until the population grows out of hand. But because of their preferred diet, they do not have a good track record in newly set up tanks. I like to let tanks go for 2 months or so ideally before adding either kind of shrimp.
*Of course, there are also ghost, Amano and many other shrimp out there that typically aren't bred in the home aquarium, as well as some oddballs
Nothing good happens fast in an ecosystem.
