So I classify myself as new even though my tank is going on a year old. I'm curious about how full is too full. I currently have a snowflake eel 12" a zebra eel approx 18"-2' (he never comes all the way out). A Koran angel a Scopas tang a clownfish and a lonely chromis and a file fishAfter adding both my eels it took like 3-4 months for my tanks nitrates to settle down and get down to the 10-15 range. I just added a file fish and the Koran to the bunch after the eels. The tank looks semi bare because the eels take up most of the bio load. I can feel like my tanks reaching capacity but not due to space but due to bio load. Any thoughts if I'll be able to continue to add after this or if my tank is truly telling me enough is enough. Also I eliminated all my corals before people say 10-15 is enough and I hardly do water changes. I'd like to not have more and just water change it out. The eels were a major shock but I wanted 2 different species and thought it best to add them at the same time. Was that just a big shock and the fish will be much less of a shock in the future. Never experienced a big spike like that with adding in tha fish before that. Never noticed any levels change. My tank is very well seasoned and I should mention it's a 125 gallon with 200 pounds of live rock. And everything is setup so the free swimmers can go around and around and never have any issues. Tons of space to swim around.
