I have a 55g display with 30g refuge with 20 red mangrove trees. I have two ocellaris clowns one male mandarin dragonette scribbles (girlfriend named him) one very cool sexy shrimp and of course snails and blue legged hermits. i have just a couple of corals blue mushrooms, two head torch coral and water parameters perfect even with heavy feedings because im training my mandarin with decent sucsess but im not to concerned with that because i have 5 completely stocked pod condos that keep him well fed. adult size is not a major factor cause i am in the process of building a 200g with 65g sump and 30g mangrove refuge.(about 6 months to fish ready) some of these will go to a 54g hex that is cycling now. I want to add one maybe two more fish i like color and personality but i want to make sure scribbles doesent have to compete for food and noone picks on him because that is my girlfriends fish and she will kill me.lol so i thought about a dwarf angle not sure on which one. but any advice is appreciated and valued. safe and balanced yet visually attractive system is my goal.
