My little daughters (5 and 3 year old) want a fish tank after winning some goldfish at the fair. Some of them died off and my oldest got really upset, so I want to get them a "real" tank.
My father has a 55 fresh water and 125 gallon salt water tank, so I've been around tanks from a young age, and they are so calming.
What is the best bang for your buck starter kit? (looking into getting a 20 gallon tank). Looking to spend no more than $150.
