I'd like to start some discussion on this thread about Tang Myths and Theories. Here are some things that I hear alot:
Tangs should be kept in tank no less than 4ft - I disagree because i have seen tank in 32" tanks and the tangs are thriving, obviously these tangs are babies and will grow fast and need moving to a bigger tank fast but they seem fat, healthy and disease free. My LFS has a tiny Yellow and Hippo tang in an RSM! These tangs will grow fast obviously but they are also thriving.
Tangs have a big affect on bioload - I have seen a 40g with a PBT (brown), Hippo and a Kole and they had 0 Ammonia, Nitrites, Nitrates and Phosphates. So IMO if you maintain a well kept system with a good amount of filtration then things may be fine.
Obviously these are only a couple of things that are believed out there so I would like to know some things that you have all read.
Thanks
Sorry Karr93 i must disagree,
The 4ft tank statement is for tangs in consideration of their adult size. Of course baby fish can be kept in smaller tanks. In reality all fish are reccomended by their adult size not infant size. Stuff such as an Orange Shoulder in a 90gal is a perfect example of a no-no of course it can fit, it won't thrive. Again the tank recc. are based off of the adult size of the fish. I believe you misinterepted.
Tangs on bio-load. Honestly you go as natural as possible:
Tangs are herbivores.
Herbivores feed on plant matter.
Plant matter has less protein than meats.
It takes more plant matter to achieve the protein amount needed to live.
The more food the more waste
The more waste the more Ammonia, Nitrite, Nitrate,Phos
More Am , Nitrite, Nitrate the more denitrifying bacteria.
More denitrifying bacteria the more waste.
etc
etc
In general more bio-load. Just because the levels of Am, Nitrite, Nitrate, Phos read zero means absolutely nothing about bio-load. I have a heavily stocked 75 gallon, Am-0 nitrite-0 nitrate-< 5 ppm Phos-0 and I know its a high bioload because my feather dusters thrive, I have a green tint to my water( planktivorous algae), I have tons of micro fauna growing. That all points to a heavy bio-load. You might want to re-phrase your statement.
If you really want to get technical the keeping of tangs in general is a crime. ( Most cases) Most tangs travels miles upon miles in schools in search of food. Even a 8ft tank isn't a mile. Those tangs are your Convicts, Atlantic Blues, Hippos, Sailfins etc. Only a smaller group actually stay in the same location for feeding ( PBT's, Pbt's)But obviously the tangs are kept in an aquarium and they do fine. Bringing up a Tang Myth and Theories movement will open a gigantic door to much more larger arguements.
