Can I add another fish?

[Ghrommi]

The answer is likely "no", but I need few more people to tell me that so I can get this idea out of my mind.
I have Red See MAX 170, which translates to about 40 gallons, and that's the fish I have right now:

• Pair of ocellaris clownfish
• Pair of banggai cardinalfish
• Firefish goby
• Pair of bluestripe pipefish
• Ruby dragonet (eats frozen)

I want to add either twinspot goby or white banded possum wrasse.
How bad of an idea is that?
Tank is 6 month old.

Think it’s fine. Your other fish are not large so another one won’t make a big impact.

Thank you, I honestly thought I should not get more fish.
