Ok, so I have a 55g which had a scooter, firefish, 2 tomato's, banded sleeper goby, and a melanarus wrasse along with my Wenn. mantis. 
 
I had a BF100 Reef Octo skimmer that I gave up on because it was flooding even if water went half a centimeter higher. (It's in tank pump but hangs off back of refugium)
 
For now I've been running the skimmer out of a 9g nano that I got.

Since sold the blenny and lost the firefish. For the 4 remaining fish + mantis, do you think I need a skimmer? I feed usually 3 pinches of flakes a day + 1-2 cubes frozen that get target fed to corals + some adrift for the fish. I do have a couple anemones, clam, and a ton of chaeto/anthelia/GSP/xenia (got rid of most of that)
 
I'm also strongly thinking of making the 9g a home for the little mantis + random coral and maybe the clam(?) to keep it safe from a peacock. I'll sell the rest of the fish probably so it's just a Peacock/soft coral/anemones in the tank. Still need a skimmer? Idea is to have plenty of hermit/snails but also target feed table shrimp to mantis.
 
 
 
If I do indeed decide I still need a skimmer, any suggestions? A ASM G3 doesn't fit my refugium. I'm having trouble figuring out what's a good brand that would also be good for 40-70gallons ish and fit in a maybe 8 by 10 or 11 space.

		 and even with this major upgrade about to begin...I am effectively doubling each systems current total volume so all up around 2,000liters for 16 stomatopods again sheer volume will maintain a very healthy system between water changes.
