Has anyone ever made a chart of fish size in realtion to tank size. In other words if a website says min. tank size is 75 for this fish, then what about comfort size. Alot of people get critasized for buying a tang that has a min tank size of 75 but everyone says thats to small. Alot of people need to know where this take effect. I'm guilty as much as anyone on this. What I'm looking for is basiclly a growth rate chart for every fish. I hope I'm not confusing everyone. I would make the chart myself if I only had the knowledge. Thanks

I honestly have no idea what you're talking about but I'll guess.
If you want to know how large a fish will be when fully grown, just google that particular fish and it will always lead you to a website that has an 'adult size' for that fish. Those 'minimum tank size' guesses are always way undersized in my opinion.

Well kinda, actually looking to know the growth rate per year on any given species and then the realtion to tank size. I mean if they recommend a tang's min tank size of say 75 then how about 2-3 years later. How big could it get and how long could a person expect to keep said tang in that tank. I may be lookin for something stupid, just curious as some people believe that if they say 75 then that fish will be good for the lenghth of it's life. But when does a person say okay my fish is to big for this tank I need to move him to a bigger one. I hope this clears up what I'm after. I should of thought about the subject alittle more before I started the thread.

I don't think it's really possible to come up with a chart, or a rule of thumb, because most of the time neither one is going to account for behavioral differences. As I've posted elsewhere, I think it's more important to go by the fish's habits and behavior in the wild, rather than just its adult size (and IMO, many of the tank recommendations given in books, even in some of Michael Scott's books, are too small).
Tangs, to use your example, are extremely active and roam widely in nature, so they need as large a tank as the aquarist can afford, really. On the other hand, you can put a 3" Banggai cardinalfish in the same 30G tank that would be impossibly cramped for a tang of the same size, and the cardinalfish would do just fine--because it tends to hover in place rather than swimming constantly.
What I would do is learn about the fish's habitat and behavior in the wild (diving videos, fish identification guides, and nature documentaries are really good for this), and factor that into the equation when I'm considering what size tank to buy.

OP is also wondering how fast each fish gets to its adult size.
For instance Aquatic Connection has advertised Blue Hippo Tang Recommended tank size 20 gal or larger. If someone was to read that there but read min 75 gal here how are they to know which one to follow. I am probably being confusing but there are people out there that need to know without a doubt what each and every fish can handle. I don't claim to know much in this hobby, in fact most of what I have learned has come from this site but what Aquatic Connection advertises can be deceptive to alot of people. There are other websites that claim the same, just can't remember the names. And NO I am not bashing Aquatic Connection, I think they are a great site, just bringing it to everyone's attention.
