Hello Can reef

[Mr.shrimp]

Hello I'm a new member and have had my tank running now for going on three years, in that time I've made some mistakes but thankfully learned from them I'm running a 20 gallon long nano with a 2.5 gallon refugium HOB with mud and cheato, two t5 ho 24'' lights power head and a blue led light strip for night time. the tank has numerous mushrooms red blue green purple and a pistol shrimp with Goby paired up, growing an astapia pest anemone getting pretty big now about three to four inches long I know everyone hates them but after hanging around for the past three years I've grown to like him. 30 pounds live rock. My levels are basically nothing as the refugium cleans the water nicely i'll put up some pics from present and past asap.
