I want to know a really rough estimate for 20lbs of liverock, a 3 inch thick sandbed, a protien skimmer, and anything else I may need. Please post every item to buy so I know how much I will need and I will be getting these parts one at a time. starting with the tank and filter and ending with the livesand. I also wnat to know if I can keep my Snowflake eel in there when he gets bigger and if I can turn his old home (a 29 gallon biocube) into a reef only tank or a hospital tank or a idk tank for random things that are to small for my big tank to keep until they can be kept with my eel. Also, my eel is about 10 in long right now how long would you estimate I have until he needs a new tank? Also, are anemones hard to take care of and can I keep one in my biocube with a clown and my eel? Please help me I can't find any help.
