    So I've downsized my tank from the 165 6ft to a 120 4ft and need to know how many if any tangs I can keep in the 120. My current tank has 2 yellow, 1 red sea sailfin, 1 purple, and 1 blue hippo. I'm selling the two yellow tangs but would the remaining 3 still be too much? I'll also be moving over my mystery wrasse, goby, lawnmower blenny, 2 pajama cardinals, six line wrasse, pipefish, and 7 blue/green chromis. I'm thinking this will be over stocked with the new tank.

    I have 21 fish in my 70 cube.. granted non are tangs and 15 are mainly rock and cave dwellers so they are not out and active and not poop machines like tangs... but 21 fish none the less

    Also I over skim lime a sob... I feed 5-8 cubes a day (8 when I broadcast feed) as well as phyto, oyster feast, ect daily..

    as far as the tangs go... they all know each other and I would expect less agression

    You should be okay with what you have if you choose between the sailfin and the purple, as they may likely become aggressive in the smaller tank. The purple would be preferable as they stay smaller and are more suitable for a 120 than a sailfin. The hippo will get too big if it isn't already, IMO, for a 120. Other than that you should be fine assuming you have filtration that can keep up with the bioload.

    I would agree with Kyle the blue tang will most likely be too big for the 120 unless hes a small sized still. What kind of sailfin tang is it? Some stay smaller some get massive!

    The blue tang is still smaller and the sailfin is a red sea desjardini sailfin tang which is also smaller. My plans are to make the rockscape as open as possible with this build so hopefully this allows more swimming area for them.

    I will be using a Bubble Magus NAC 77 for a skimmer (rated for 210-315g), Vertex ZF-30 for biopellets, and a BRS Dual Reactor for Carbon/GFO if needed. I think this should cover me for filtration hopefully!

    If I had to choose I would definitely be keeping the purple tang and sailfin out of all the others as I've seen some huge blue tangs I will eventually rehome it once it gets bigger and I have decided that the yellow tangs will be rehomed before the move to the new tanks.

    Thanks everyone!

    With my experience and Tangs, I would go with (2) in a 120g tank. They will only grow to how much space they have but they will grow. After putting that out there, I would chose the (2) that you like best or believe will get along the best. Then I would find new homes for whoever is not part of this elite group you will have.

    At some point in the thought process, you need to consider who will grow the most and who you want to see grow that much. You always need to think of what kind of space they will need compared to how much space you have. Happier fish make for better tank mates in my opinion.

    Agreed, I think I have settled on the Sailfin and Purple tang as permanent residents. The Blue Hippo being small still will be only temporary till I feel it's grown too big for this system.
