    Only ever kept the single specimen I still have so am wondering if the different species exhibit varying degrees of aggression towards one another and other fishes? If so, which of those available in the trade are more/less aggressive?

    hi Matt
    r. duospilus, leavelli, rubromaculatus: ignore other species. not agressive in sense of attacking directly other specimen. in degrees: duospilus, rubromaculatus, leavell. in case of the last: females avoided direct contact with the male, leaving the place whenever he appeared.
    J. Baur and M. Taxacher have certainly more infos.
    cheers Charles

    only ever kept one species Matt, same as you, and I thought the aggression was all ‘handbags at dawn’. Never saw any damage to any of the fish I had.

    Hi Matt,
    like Charles said: almost all Rhinogobius Species are not interested on other species and ignore them the most time.
    There are exceptions. If for example an A. australe attack R. duospilus (which they love to do), the goby will defense herself. But they never takes on its own initiative.
    Meanwhile, more and more from the duospilus complex come in the trade and recently appeared with us a rather aggressive species: R. ponkouensis. Their females real attack of itself to other fish. It is therefore important to look closely when purchasing.
