Has anyone planned their tank from one fish and worked backwards. For example I plan a 130 gallon peninsula type aquarium and a biota goldflake or Regal Angel , possibly one anemone , pair of clowns etc. How would one research from this point ,type of corals , rock work for aesthetic but more importantly hiding places for each chosen fish , how many fish and types of fish . Then introduce each fish according to its aggression or it’s ability to live with other species ?
