How do you cope with new arrival aggression?

[Tinnerito]

I want to restock my 6 gal after the crash, and currently only one clownfish is left. He did great for the few months there were 2 other fish since I only got each one about 2 weeks apart. But now he's been alone in there for several months now, and I fear he may be territorial against a new fish since he knows the tank in and out.

So my question is, how do you add young, new fish to a tank with already well established ones? I've read adding a mirror helps but how effective is it really?

I understand. I take absolutely no offense as you make the most valid point there could be. And as controversial as this may sound, I have to disagree. Over the course of a whole year I have kept no more than that one ocellaris, and a neon cleaner goby as livestock. During that time period, they ate actively, each found their own sections to call home, grew a lot, and were very social, and very much healthy; and a healthy fish is a happy fish. My clown loves my caulerpa cluster, and spends most of the day around there, bobbing and nudging, and sometimes likes to play at the top of the tank by the return pump. Happy clownfish :smiling-face-with-smiling-eyes: . My neon goby loved traversing the many small caves I have provided, and even had a little "crater" it loved to sleep in every night. Happy goby :smiling-face-with-smiling-eyes:. I also had a very plentiful clean up crew to combat nutrients, consisting of 5 nassarius snails, 1 bumblebee snail, and 3 red legged hermit crabs. They all kept up with the bioload amazingly, and I occasionally fed them a piece of raw salmon, cod, or mackerel since obviously the bioload alone wouldn't be enough. Additionally, I had a canister filter fit for a 40 gallon aquarium. It did wonders keeping mine pristine since it was so much smaller.

Sounds crazy for such a small tank I know, but I've been keeping freshwater fish by myself with my own income for almost 9 years. I even kept a mahano shrimp in a 3 ounce pen box for it's entire lifespan succesfully (for context it was on accident as it would be eaten in any other tank and I simply got the shrimp for free when buying some snails)

Anyway, the crash of my 6 gallon occured due to me letting 5 corals die at the same time in that small tank because I am still a newbie at corals. Just not fish and inverts. This brought my nitrates from 7ppm to 80ppm killing all of my clean up crew, and sadly my goby.

I appreciate your advice, but all I really want is for this tank to be in the same shape it was just a mere few months ago. Also, major respect if you read all of my yap.
