fish stay on one corner

[cherrmin]

hello, i recently added some fish to my 75 g tank and i noticed they all stay in the corner near the filter. I also my tang picking at the filter, could he be picking at algae growth and is that why they’re all there?

Possibly since that butterfly also eats algae. Is there any other behaviors like other fish chasing them or heavy breathing?

no, if anything they’re just all together and there are no signs of aggression at all

It could be lots of things. Like flow or not enough rocks so they stay close together for protection.

How long has the tank been set up? And a full tank pic would help
