So i have 4 african chilids and was wondering if it's safe to mix like 2 inch cichlids and 1 inch cichlids in the same tank? I don't know what type they are. I bought them at walmart and they were all mixed up togeather! They are curently in a 55 gallon tank. I look at them when they eat and it seems the little one dosen't eat? he just hides! Is he scared to eat becuase he'll get attacked? some please help me out! I'm sorry i'm a newbie!
