Ok, I just started a 2.5 gallon reef tank with a sand bed of 3 inches, a few pounds of live rock, a Shark filter with with nothing running in it(Shark filter is like the Fluval one filter) A PC 50/50 JBJ clamp on light. I have a few frags in a 55 gallon display tank at work I wanted to put in my 2.5 gallon tank. I just wanted to hear some input on which corals I should start with. I have a frag of leather coral, finger leather coral, and candy cane coral. I was also going to put a catalina goby in also, let me know what you think?
