    When visiting an aquarium shop it is always tempting to buy lots of fish.
    This often leads to disapointment especially in new aquariums.

    Here are our simple ideas for successful fish introduction.

    1. Take it steady, less is definatly more in the end.
    2. Try to choose and understand the fish you want and its needs before going to the store.
    3. Try to make sure you minimise the time your new livestock is in the transport bag.
    4. If its extremly cold or hot provide an insulative box to protect the fish.
    5. Float the fish in an open bag on the aquarium and change part of the water as you go.
    6. Provide hiding places for the new fish and existing fish.
    7. Reduce lighting while the fish are being introduced will reduce stress levels.

    If you have a seneye device you may want to place it the bag with the fish so you can check the key parameters as the fish are floated and see the difference between the bag and the tank.

    If the water parameters in the bag are very close to yours then floating time can be minimised.

    Often fish kept in transport bags for long periods will start to use up the waters oxygen and replace it with CO2, this intern lowers pH and allows the toxic NH3 being produced in the bag  to turn into non toxic NH4. Once the bag is opened oxygen will replace CO2 and the pH will rise. Also pH can rise or lower when adding water to the bag from an aquarium with a higher pH. A pH rise will increase NH3 levels the larger fish the fish the more noticable it will be. Again a seneye device in the bag while floating will help alert you to any raise in NH3.
