My male and female kuhli loaches (Lily and Leo) have been exhibiting cute but strange behavior. Occasionally they will "doggy pile" each other randomley, wiggling and squirming over each other and it looks like they're trying to tie a knot in themselves, and then Leo will slide up to Lily and vibrate his tail against her side. Now, kuhlis are the most peaceful fish ever, and aren't aggressive. If anything, it looks like they're cuddling! They even "kissed" (their mouths touched) for a couple of seconds!
I'll try to get a video, but in the meantime, anybody know what this behavior means ???
