210 gallon Dream tank

Interesting fish behavior.

So it seems 2 of my maroon clown fish pairs have befriended yellow tangs in two different tanks.

210 gallon tank
Just added this yellow tang, and the lighting maroons were added a week or so ago. First night yellow tang was hiding on other side of the tank. The very next morning I find him sleeping in literally the same exact cave as the maroon clownfish. They show zero aggression towards the yellow tang. But they chase away any of the cardinal fish that near their cave.

40 gallon sps tank.

The yellow tang in this tank isn't maybe a half inch to a inch bigger than the new one. But he's gotten is full vibrant yellow coloring now.

The golden nugget maroons in this tank are my second biggest pair. 1.5-2.75 inches. They also have made friends with this yellow tang. They hate the foxface fish to the extreme, and get annoyed with the six line wrasse when it starts it zipping around them game. But they ignore the cardinal fish in this tank.

Full tank shot of 210.

Tomorrow I would like to get the addtional kessils installed on this tank. I may also consider adding 1-2 tester hammers, and maybe some other random lps corals to see how they do.

Why are you not adding more of your toadstools for now before adding more demanding corals?

That's all the bigger ones I have, in have a few smaller ones, I care alot more about. Yet looking at the current rocks structures and layout I would likely fill the tank up with what's left in the frag tank especially trying to space out torches and hammers.
 
Breif update:

So far it seems like tank has hit the ugly stage with a diatom outbreak.

Slight issue with the banghi cardinals.
2 weeks ago I started with 3, added 3 more the very next day making a total of 6.

A day after adding the other 3, 2 went missing. 2 days later I had four left.

There were 4 in the tank for a entire week and as of 2 days ago Another disappeared leaving me with 3.

They only disappeared 1 by 1. I suspect maybe one of them has turned murderer. As I see a pair of sorts hanging together on one side tank near maroons and tang, the third is isolated on the far side of tank and seems scared to go near the other 2.

They have grown so quickly in 2 weeks it's absurd. They went from the size of a dime, tk being the size of a one of the rarer 50cent coins. Doubled to tripled in size. 1/4 inch to almost a inch in other words.

All fish seem happy, healthy and getting along. One of the Cardinals is way bigger than the others maybe a male eliminating competition idk.

I've not witnessed any direct fish aggression, I haven't seen any bodies, and I haven't seen the missing fish even at feeding time. Tank has screen covers so no way they jumped.

Lastly I was able to add 2 more kessil 360xs to the tank last week.
