Also, I feel like I have a lot of fish in a 50g tank:

6 Green Chromis
Yellow Tang
Chalk Basslet
Sixline Wrasse
Saddleback Clown

Does this seem like a lot of fish to you guys?

I don't think it is a lot of fish but I note you have a tang in a two foot tank.
Your tank is too small for tangs.
Canadian, I think you know that tangs require swimming room. If you watch them they scoot from one end of the tank to the other unlike many fish that kinda just hang around.
That is why large tanks (6 foot) tanks provide the optimum size for keeping tangs. They can do what they do best, swimming.
