My buddy is selling me his 45g, already cycled that houses a blue damsel, sand puffer, 2 crabs, a few snails and a peppermint shrimp (along with live rock that has some Coraline growing) anyways, the tank has been up and running for only 5 months. When I asked him what all was included, I noticed he didn't include a protien skimmer. I asked about it and he said he doesn't use one. Never even used one on his 90g (that is doing amazing btw). So are they just an addition if desired or a neccessity? His 90g has been up for over 2 years without a skimmer???? Just need to know if I should purchase another or just leave it alone. It's a 45g TALL tank
