I have a 90 gallon with a 20 gallon sump. I have a little mini fuge going on in my sump. I have a bowl with a little bit of cheato and a couple of pieces of rubble rock. I have about 95 lbs. of live rock. For fish i have 3 green chromis, 2 tru perc clownfish, algae blenny, yellow watchman goby, purple firefish, flame angel, royal gramma and a foxface. Remember my fuge is just a little bowl but its still something. Would i be able to keep a mandarin without a problem or no?
