or start with a few damsels then upgrade to an angel or butterfly then when your tank is established, get a snowflake eel and watch him get bigger as your fish population gets smaller......sigh. I have a 125 that im moving into its final spot i build in my living room, so it will look like a tank in the wall. get yourself some live rock after a few weeks with the damsels (say 3-4 damsels) then once its established, figure out what type of fish you want, Lionfish and damsels will work if you dont want the damsels anymore. my 125 once i move it and i re-establish everything im going with a bunch of damsels or dominos, cheap little fish. Im going more for the colors and quantity then larger fish. a larger tank with 250 lbs of live rock and good lighting, im not concerned with aggression, since there is alot of room for territories. good luck and be patient with the saltwater set ups, they take time but once established, they will give years of enjoyment
