well as per your own words the bacteria doesn't care what the ammonia is. now its pretty easy to avoid over producing ammonia by watching your levels and removing the shrimp when the appropriate level is reached. at no risk to the fish.
may I ask how food will over produce ammonia? I mean you feed the fish, the fish processes the food, poos it out, same amount of ammonia is generated in the end whether the fish eats it or not. the only way I can see the food over producing ammonia is by over feeding which you could easily do while cycling with a fish. I would suggest some one would actually be more prone to it because they are actually feeding something instead of an empty tank which doesn't have the same draw for the urge to feed it just a little more.
to me its simple economics .39c shrimp OR 3.99 damsel 9.99 bottle of amquel, Oops missed a dose of amquell another 3.99 fish. its less of a risk, and just as effective to use a shrimp.
Now the original poster also said a more biologically sound bacteria.... HUH? this in my opinion is pure nonsensical whimsy, though much of what he states is relatively accurate, that statement is pure bunk. the bacteria is the same no matter what the ammonia source is, you can use straight pure ammonia if you like, the bacteria is going to develop the same and at the same rate. the is no actual benefit to cycling with a damsel Unless you want a damsel in your tank forever, otherwise your going to have to catch it. hes asking for quotes of fact showing tangs should have at least a 6 foot tank, WHERE on earth or what mad scientist concocted the rule the bacteria is better when you use a fish? I would love to see some research to back that one up.
Now as for the six foot rule of thumb for tangs. I consider a six foot tank the minimum size tank a tang can be kept relatively happy for the duration of its life. I agree a 12 foot tank rule of thumb would be better. sure you can keep a smaller tang in a 4' tank but its going to outgrow it. I agree the overall footprint of the tank matters but really have you ever seen a six foot tank that's only a foot wide? not usually. tangs can cruise a quarter mile of reef in no time I think the 6 foot rule of thumb is bare minimum. tangs are free swimmers IMO a 20foot tank is pretty good for them.
Now of course this is all just my opinions and my views from my experiences reef keeping. I am in no stretch of the imagination a scientist, but you see enough damsels die from improper cycling and why on earth would you recommend it? I will recommend the safer route every time. ESPESCIALLY to the inexperienced.
