1 convict tang 1 blenny 2 clowns and their anemone.
You are already at your stocking limit for this size tank with this list.
A school of 5 adult Blue/Green chromis would also be too many for 65 gallons with any of the above.
My suggestion:
3 Blue/Green Chromis
1 Blenny, Midas blenny would be great
2 Clowns
I'm probably going to get blasted for saying this but it really depends on several factors. Amount of Live rock, skimmer or other means of nutrient export, type of fish, and here is the kicker...MAINTENANCE SKILLS. Many veterans can keep more fish than the rule of thumb, but they know how. You may know how...? I think a Bristletooth tang would be the only family of tang you could possibly keep in that size tank (kole, tominsis, etc). Personally, I think it is hard to give advice here as to the schooling fish. I think some flasher wrasses or some kind of similar looking wrasse would be great for you, but you need to ultimately choose what you want. Good luck!Wait a minute i got 4 fish in my 29g biocube, which is about only 20g of realestate and everything is well; and in the 65 G only 6 fish would fit in ???? it seems a bit short.

Flasher wrasse will shoal together. You just have to be sure to add all the fish at the same time, and add only one male.

Hello,
Unfortunately there are not any fish that will "school" in the aquarium. There are many fish that will shoal though.
IMO Damsels and Chromis are not the best choice for shoaling fish. They can get aggressive and they just to not add the personality that many other fish can.
I really like the Blue Eyed/Longspine cardinalfish.
Another thing to consider would be dartfish. I think that a small group of these sweet little fish would look nice:
I also like the idea of a harem of flasher wrasses. One male and two or three females. These fish add so much color to a tank, and display many different color patterns. But you will need to keep the tank covered to prevent them from jumping out.
I would steer clear of any tangs. You could keep a smaller tang in a 65, but the small space would likely lead to aggression.

When fish that normally have huge territories are put into a small tank, they can become very aggressive. Since the tank is so small, they think every square inch is part of their territory.

I would say 2 or 3 firefish, they are so beautiful, but jumpers
Chromis definitely shoal. I have six greens in my tank and they hang together everywhere they go.
