Kuhli loach eggs?

Hi guys
a bit of a hard one as I am away from home at the moment so information is not first hand.
I got a call from the person looking after my tank today and they said there is a long string like a necklace 30cm long with oval egg like things dotted along it, greenish in colour. I have two loaches in my tank one a stripped tiger Kuhli and the other is pink. Is it possible that they have bred and spawned as not sure what their eggs look like. Also, could two different types actually breed? The only other fish in the tank are neon tetras, a bristle nose and a kribensis cichlid.
