i have one in a FO tank at college, little bitty guy but hes a mean SOB. Fights w/ fish 3 or 4 times his size. Is it this guy??
There are a few chromis' that are purple or pink
The top one is sometimes called a Purple chromis or strawberry chromis. Pretty low maintenance, reef safe but could eat small shrimp (have to be pretty small) semi aggressive.
The bottom one is a Fridmani Chromis (spelling?), more peaceful.
Both eat variety of frozen foods- brine, etc.
Is it one of these, the strawberry is about half the price of the Fridmani chromis.
