I was at the lfs
and i noticed that she got in a bicolor angel. Right now in my tank i have a blue devil damsel, and i was wondering if it would be an okay addition to my tank. my tank is 20 gallon high, with 130 watt pc
. it has about 30 lbs of live rock. do you think that he would be okay in my tank or will it get to big, since on liveaquaria it says they needs a minimum of 30 gallons.
