Fish Compatibility In A 90Gal Aquarium

[legulli]

Good morning!

I have a 90gal aquarium which I acquired with an existing group of inhabitants:

-Scopas Tang
-Yellow Tang
-Foxface Rabbitfish
-2 Pajama Cardinals
-Flame Hawkfish
-Handful of Hermit Crabs
-2 Rock Nems
-2 Palys/Mushrooms (Not Sure On Kind)

My question is... How many fish/inhabitants would be appropriate for a 90gal set-up?

Some I'm interested in (could use guidance and obviously not all)... Octopus, Starfish, Lionfish, Anemones, Puffers, Clowns, Gobies, Eels, etc

Any advice?

Octopus

Very specialized requirements and short life span. Research carefully.

Starfish

Depending on species can be appropriate or not.

Lionfish, Anemones, Puffers, Eels

I would recommend researching each of these. We have a very good search function to assist with your research.
