    Empire gudgeon

    I got a couple of these at the CCAC Spring Auction but one of them took a 7'-0" dive out of the tank and onto the concrete floor a few months ago. Now I just have this one. He was looking especially radiant this morning so I snapped a few pics. (I really need to clean the glass...)

    When I bought them I was hoping for a pair so I could spawn them but after reading about that process online I decided that probably was not going to happen. Especially now that I only have one...
    From the "Seriously Fish" website:

    REPRODUCTION: Rarely achieved in aquaria and this is undoubtedly attributable to its complex amphidromous breeding strategy.

    In nature adults live and spawn in freshwater streams but the initially pelagic post-hatch larvae are washed downstream to the sea where the post-larval fry spend the first part of their life developing in marine conditions.

    Once maturity is reached the fish will spawn readily in aquaria with males intensifying in colour and attempt to entice females to spawn with them whilst defending their chosen territory against other males.

    Up to 3000 tiny eggs are laid on a pre-cleaned solid surface which may be a rock, piece of driftwood or even the aquarium glass.

    Post-spawning the female is rejected and the male assumes sole responsibility for brood care.

    Incubation is around 24 hours and in the natural life cycle the fry would now be carried to the sea, where they feed around the coast and in estuaries before returning to freshwater to spawn themselves.

    Provision of such conditions plus the tiny size of the post-hatch larvae thus present serious problems for the aquarist.

    The larvae initially have no alimentary tract or rayed fins initially and are even unable to accept infusoria-type foods.

    If you're up for the challenge, there are still quite a few at the reef. We have had them since before the auction (same ones) so we might be able to work out a deal.
