Just a little back ground. I've just started in this hobby my tank has been up for about 6 months now. It has been a learning process to say the least. I have 120 gallon with an RS 200 sump. I currently have the hardiest fish known to man. My pride is my Niger Trigger we have been through a lot. I have 2 clowns, a long tentacle anemone, purple fire fish, yellow watchman goby and pistol shrimp pair, sailfin blenny, diamond goby, and a cleaner shrimp. I have struggled at keeping tangs or angels alive. I do have cheap easy coral to start with. I have a Kenya tree, some xenia, star polyps, and an orange Gregorian I think it's called.
