The topic of crayfish burrow co-habitants came up once before. Its not
well-documented but there are at least two short articles on the subject. I
suspect there are more, especially in the older natural history literature,
but I have never gotten around to looking for this kind of information. The
two articles that I have seen are:

Creaser, E.P. 1931. Some cohabitants of burrowing crayfish. Ecology 12:
243-244. [Invertebrates]

Neill, W.T. 1951. Notes on the role of crawfishes in the ecology of
reptiles, amphibians, and fishes. Ecology 32: 764-766.
[Fishes - I believe that study was based on a combination of direct
observations of excavated burrows and on fish seen in previously dry ponds,
but am not sure. Have not looked at this article in a couple of years]

Here is a list of some organisms known to share crayfish burrows: seed
shrimp, copepods, amphipods, bluefin killifish, pirate perch, banded pygmy
sunfish, tadpole madtoms. Suspected crawdad roomies include: mosquitofish
and grass pickerel.

Also - I've seen golden topminnow and flagfish miraculously appear in
formerly, dry isolated wetlands in near Tampa, Florida and susected that
they may have been lurking in burrows.

Also, consider that not all crayfish burrows are occupied; I have frequently

dug into a crayfish burrow until I came to its end without finding anyone
home :)
