can various Nannostomus species crossbreed ?

[anewbie]

Per subject can the various nannostomus species cross speed. in my specific case i ended up with trifasciatus and mortenthaleri in the same aquarium but don't know the rules for this genus crossbreeding if at all.

Hybridization is unlikely.

Between these 2 species, very unlikely. But many "species" of Nannostomus are actually superspecies composed of several different species. These are more likely to interbreed.
