I am getting a fish only with live rock tank. I think it is going to be about a 90 gallon tank. How much live rock should I have? More importantly, I want to get a picasso triggerfish. What kinds of other fish can live with a trigger? Are there any eels that would be ok in the tank?
Thanks

General rule of thumb is 1lbs. LR per gal. You can also mix base rock with live rock in order to cut cost.
FOWLR
There are many possibilities for fish selection. Dr. Fosters and Smith Live Aquaria Site has a compatibility guide that may help.

Several eels (snowflake, Diamond Back, etc.) will probably be ok, but some when fully grown may get a little cramped.

I have a picasso and an undulate trigger with two clowns, a coral beauty and a foxface rabbitfish in my 55 they are all doing great any of those would work

If it is 90 gallons you a have quite a few options.

For eels you could do snowflake, chainlink, or zebra. Those are the only three that I feel could live happy in a 90 for a long time with other fish.
A picasso can become a very bold trigger with age so you are going to need tankmates that can hold their own. I would say no lions, other peaceful triggers, or butterflyfish.

I would look into something like this:
Picasso Trigger (bold and lots of personality)
Any eel above (interesting conversation peice)
Flame angel (can hold its own and vibrant red)
Pinkface Wrasse (Very colorful but smaller size for a wrasse)
Yellow Tang (Some people will say no tang in a 4' tank, but if you get it small enough I think it will be ok for awhile)

Thats what I would do. If you have other fish that you like just post them and we can make a new list.
