Do I have too many fish?

[sunlooper]

I have a 14 gallon cube, that’s filtered by a Fluval 107 canister filter. I used Tropic Marine Pro Crystals and I also have Chemi Blue Pure Elite in the canister.
Fish that are in the tank right now: yellow watchmen goby, pistol shrimp, naked clownfish, tux urchin, banded coral shrimp, Orchid Dottyback and two corals.

Please be honest and any advice to keep this tank running.

What are your water parameters? Do the fish fight for territory? That’s what I’d use to determine if you have too many inhabitants.
