hi guys, recently i have acquired a 30gal SW
tank with live rocks only. the previous owner had a humu triggerfish in it and i knew it would be happier if rehomed to a bigger fish tank, which is what i did. now my tank is empty except one hermit crab and a few snails. since i'm new to the SW
side of fish keeping, i would like to know what are some of the hardy fish out there that a beginner like me can try in a 30gal tank. i would prefer their diet to be flake with occasional frozen treats because i have a job that requires me to travel and i would like to put the food in the automatic feeder. i understand a variety of food is good but considering the circumstance i will have to do flakes 60-70% of the time. i will treat my fish to a feast of frozen/live shrimps periodically especially before i go on a trip. with that been said, what are some of the beginner fish that i can try?
