Do Dartfish share burrows with gobies?

[Zionas]

I read from Scott W. Michael’s book that they like to share burrows with shrimp gobies like the Yellow Watchman. Is that true? If so, have you seen it in your tank?

Which species of Dartfish do it? Only the Blue Gudgeon or both the BGs and the Scissortail?

This is what I mean. Pretty cool.
