    Has anybody witnessed Corydoras getting below the substrate? I currently keep 5 Corydoras species and have twice witnessed C. aeneus diving under the gravel. I keep other Corys. over sand and haven’t seen it with these, just the aeneus.
    Odd behaviour or common?

    I’m keeping some nijsseni (with gravel) but can’t say that I’ve observed this.

    I’ve seen it with C. carlae.

    Graham, do you think the C. carlae were after food? I am not sure if mine were doing this for food as they were stationary deep in the gravel.

    No it’s not feeding behaviour. They used to bury themselves in the sand and only the top of their head and back was showing.

    I mentioned this to Hans George Evers and he thought it unusual as C. carlae are found over hard substrate in nature with little opportunity to dig.

    Which doesn’t mean that they won’t if they can

    Stefan, you maybe right but I don’t think all Corys do it?

    I considered that it could be a way of dislodging parasites, but then Corys would not be prone to these (especially in a controlled environment).

    Could some other fish be spooking/harassing them?

    Definately not; only other species are one Rhineloricaria sp. and four Tanichthys micagemmae.

    Are they “itching” themselves in the substrate?

    I think something along these lines is most likely. I always took it as a sign I was overdue a water change when they did it.
