    Guys and gals,

    I need some advice on fish stocking. I have a 1200x600x600 tank with the following current livestock. 3 x chromis, 1 x banghai cardinal, 1 x large clown, 1 x small clown, 2 x cleaner wrasse, 1 x large foxface, 1 x picasso trigger, 1 x banded shrimp and 1 x cleaner shrimp.

    I have the option to purchase 2 x purple fire goby, 1 x yellow tang, 1 x regal tang, 1 x flame angel and 2 x cleaner shrimps from someone shutting their tank down.

    My question is am i overstocking?

    Justin

    I think that your current stock level is already nearing max capacity for your tank. But lets hear what others regard as max capacity for a tank of that size.

    I have 15 fish same tank:
    3 chromis
    2 orange clowns
    2 black clowns
    1 lawnmower blenny
    1 bi-colour blenny
    1 yellow tang
    1 flame angel
    1 regal tang
    1 CBB
    1 cleaner wrasse
    3 peppermint shrimp
    1 flame shrimp
    1 cleaner shrimp

    Still wanting a tailspot blenny.

    well i will give the answer based on biology
    the way i test for over-stocking based on biology is the time it takes your tank to recover from feeding and the new addition.
    if you running at NH4 = 0 NO2 = 0 and NO3 = 0 and you add 2 fish, after the spike your parameters should go back in a day or 2, if your nitrates are sitting say 10ppm+ then your biological filter is overworked, adding more surface area and bacterial supplements will help.
    also remember you will be feeding more

    now for the physical stocking, well this is subjective to the owner and temperament of the fish, no fighting, no whitespot then you good.

    but thats my view

    What is the size of the regal and the YT?
    i think that your tank might be a bit small for them...

    Does seem like a fairly big amount of fish with the new addition, will be a total of 15 fish. If you got a powerful skimmer and running bio pallets or zeovit you could get away by adding the new fish in but has to be on done slow intervals and keep a eye on your important parameters. Hope its not a problem, Goodluck.

    Guys and gals,

    Thanks for all the advice. It didn't feel right so I've declined the offer. I health of my existing fish is more important than a bargain ;)
