I really want a purple or yellow tang.My tank is 40 gallons.I plan very soon to get about 45 lbs of live rock.Here is my original fish list:
1 royal gramma
1 pair of ocellaris clowns
1 coral beauty angel
1 six line wrasse
I also want some inverts,and maybe a few mushrooms.could i get a purple or yellow tang(I'd prefer a purple).Could i get one at around 2-3 inches and when it gets to large take it out.I'd replace the six-line or the royal for a purple tang.Yes or no?, i've heard of tons of people who have done this same thing. Thank you!
The 5 fish you have listed will be a full bioload for a 40g tank. Save the tang for when you get a bigger tank. Tangs should be kept in at least a 4ft long tank of 75g and larger. Some tangs, however should not be kept in anything smaller than 135-180. It depends on the species. For a purple I would say 75g minimum when small and at least 100g when bigger.
