    I was looking for my mandrin as I had not seen it for a day or two. My pod population is still overgrown and he was a fatty. Today I was doing a 80% water change and noticed him at the back of the tank on the floor, looking rather like biltong.....

    I would not have expected a Mandrin to be a jumper???

    Second fish in a month....

    They jump if needed. Many mandarins were found outside the tank. Clowns do jump as well. Probably almost any fish will jump, if needed.
    The question is, why did he jump. If he jumped, any other fish in your tank might do the same one day.

    Yup I am considering a top either of egg crate or a frame and fishing line in a net.

    Any other ideas ?

    Yup they are known to jump. many fish will jump if given a fright or when picked at by another fish. this mostly hapens at night

    That is why I always prefer a tank with bracing right around. Moonlight would help that the fish can see what's going on at night.

    mandarins rush to the surface in their mating process so it it possible for them to overshoot and land outside but yes unfortunatley fish were not designed to be kept in glass boxes and know no boundries unless it is goverened by a mesh net or something, so if you have an open topped tank.. expect to find a fish on the floor at some stage...

    My new tank has bracing around the edges, but how does that stop them, do the fish usually jump along the edges of the tank?

    its difficult to say but im guessing in most casses it would be along the edges they are most likley to breach while russing up against the glass so braces will help to an extent but are not going to exclude jumping as they may jump from the middle.. a mesh would be best or go with a lower water level in relation to where the glass ends i have a 7cm gap between my top rim and water level.. but its not 100 percent jump proof...

    I run a high bio load and prefer doing large water changes. Currently manual but in my new tank which has finished cycling it's automated :)

    Strange that they are jumpers, you wouldnt think so. my Scooter blenny jumps almost everytime I do maintenance in the tank....He spooks very easily....may be a wild caught thing.

    Every week. Make sure the temp and ph is the same and away we go....
    Then add enough Special Blend and Brightwell Iodine, Kolor (Product) and Trace elements.


    I wont need to do this in the new system. It's got Zeovit and has a automated waterchange system tested it yesterday.

    Got mixed salt water stored in a tank, I go up to my Profilux say water change :) it opens a valve, turns on a pump in the a chamber in the sump and dumps 10% of the water through a 40 drainage pipe I just installed.

    It then reverses the process pulling in salt water. Have to add another salinity probe to test salinity and then changes the valve on the chamber pump to pump salt back into the sump to be sent to the DT....
