I added 2 Pajama Cardinals a week ago and now my Firefish gobies are gone

I added 2 Pajama Cardinals a week ago and now my Firefish gobies are gone.
I've looked around and don't think the firefish have jumped out.
Any ideas? Are the firefish hiding?

 

Welcome to Fishlore hope our salty members can help you today

 

Fire fish are fairly shy and easily get picked on. I’m guessing they are hiding because of that. Keep an eye out for them.

 

They are back! Actually they came back out of hiding a couple of days ago, but I've not had time to report.
Anyways, the cardinals don't seem to be chasing them so I'm not sure why but they are spending more time hiding and less time in the open than before the cardinals arrived.

 

They are just shy fish. Cardinals are peaceful too. They should do ok together. Just make sure everyone is eating.

I have a 65 gal. FOWLR I have a cleaner wrasse (Lil' guy), a yellow meringue (white belly) wrasse (boss of the tank), a watchman goby/tiger shrimp, 2 firefish, 2 PJ Cardinals, a choco chip starfish and some snails & conches.

I would like to add to this, what would you suggest? I really like the peaceful vibe going on. The only times I had any animosity in my tank was with the yellow wrasse and the molly and also the yellow wrasse with a royal gramma. The meringue is more aggressive than usually described.

Sorry what would you like to add? I wasn’t catching your question?

My bad, I would like to add more fish, I don't want to overwhelm the system though. But I think a 65 gal. could hold 1 or 2 more fish.

I love my shrimp/gobie combo but not sure if other crustaceans would work in there.

You could probably add one more small fish. Small goby or wrasse. I’m cautious with saltwater tanks.
How much live rock do you have?
What crustaceans are you considering adding. No red flags fish wise. You could add another goby shrimp pair. I love them!!

 

Not as much Live Rock as I want yet. I was think of making something out of pvc to prop them up out of the sand more.
Can multiple gobie/shrimp combos work? I was wondering if the shrimp would fight? I haven't considered what other crustaceans, I am open to ideas.

I’d concentrate on more rock before anything. Pistol shrimp shouldn’t fight. They will find their own homes or hang out together.

 

Thanks. Good advice.
