Recommendations for Cave Dwelling Fish

[RFURBP]

Hello,
I have rehomed my snowflake eel, but now have large pvc pipes on the bottom of my tank. I do not want to go through the hassle of taking all the rocks out to get rid of it.
So are there any reef safe fish that could utilize the pvc pipes as a home? The system is bare bottom.

Royal gramma

Almost the same as the royal gramma, my orchid dottyback has a cave that she goes into at night.

court jester goby, mine loves to hide in the rocks and it even builds caves for itself. they also take care of hair algae & algae on the sand if you have any

Basslet of some kind

I was hoping to find one that will spend a fair amount of time swimming in and out of the two, 3ft pieces. Basslets are an interesting idea. I'll keep the royal gramma in mind too. My tank has no sand so it rules out a lot of gobies.

Marine betta?

Marine betta?

While Betta's are cave dwellers in the wild venturing out to hunt after dark it would take pretty large pipes to keep one happy. I'm not sure they'd make much use of them as pipes either except to hang out near to end of it.

Because you have great hide spots, I’d seriously consider a pair of orchid or springers dottybacks, or grammas. They pair easily when young (IME) and their behavior as a pair is loads of fun to observe.

You’ve paired royal grammas?

Are you against another eel? I'm partial to Zebra Morays. Super cool and very chill. Not escape artists and don't bother a thing

Yep! They lived together and shared a cave for about 2 years before I lost the smaller one, which I assume was the female. Lost the male maybe a year later. Not sure if it's just me, but in my hands they didn't seem to be a very long lived fish, which was a bummer. My male was the biggest one I've ever seen when I lost him, and they started out pretty small.
