Are there any cave dwelling fish?

Assembling scape for my new tank and I really like this rock, it's fairly large. Tank is 130g. It's not a through cave but maybe I could knock some holes into it. I figure worst case, a cleaner shrimp might occupy it. Any peaceful fish that might occupy this area?

That is very big but a watchman goby might although they could also maybe dig a hide out on the other side of the tank entirely too lol

Ya, I think that's a common thing I'll find. It's not like this will be the only channel or cave, this will just be the biggest cave that doesn't go anywhere. I think I'm looking for something that doesn't make caves, but does enjoy them.

Basslets tend to hang around caves, your typical royal gramma or blackcap comes to mind.

My blue throat trigger dug out a sand hole in a cave and grunts at anyone who passes by the cave.

its a wide open cave that doesn't provide any real cover to the fish. Its hard to say if a fish will stay there, it might get used or it might become unused wasted space. IMO

My watchman would hang out near a hole in the aquascape, but it was a lot smaller than that

basslets, assessors, my marine betta loves his caves.... so does my toadfish in his solitary tank (will eat other fish)

The larger of my Harlequin tusks likes to be in a cave quite often.

Blue gudgeons love to hide in caves. Not sure if it would work, but might be large enough for them to feel they are hiding and still be seen. I had a group once and they hid for a long time, but then started coming out at feeding time, and we loved them.

Now those are cool! Never even heard of those!

Yes they are. Ours were bright blue almost metallic. Absolutely love watching them when they allowed it.

assessors. they even swim upside down apparently

I have a priolepsis goby that spends all of his time hanging upside down from the roof of caves. Even swims upside down when he darts out to eat.

Marine betta for a cave that big.

They do, I have one. Pretty cool and I'd always hanging out hiding unless it's feeding time.
