2 in.=5 gallons

+5% gallons if agressive

+10% gallons if really active

-5% if sluggish or slow moving

if fish is bigger than 3 in = 1in per 5 gallons

add 15 galons if bigger than 5 in.

Question: what's your source? If you created this, how did you come up with it? And how do you reconcile this with a fish like a yellow tang, which would need like 70 gallons?

I read from different books and looked online and this what I came up with do you have something to add or change

In my very humble opinion, I just don't see how this would work. It's too generic. And all fish are not created equal.

Oh, and I know I'm math illiterate.... but I don't get the percentage signs.

I'm with the above posters. You can't pigeon hole a fish.
Aggression and schooling isn't taken into consideration.

Linda, you're not alone with the math. lol

Jaysee is sending subliminal messages? lol

Edit: Ooops missed the % for aggression.

This is for saltwater only, right?

So if I am doing the math right, then an 8-inch yellow tang could go into a 23 gallon tank?
because 2 in =5 gallons, so 8 inches = 20 gallons.
And then lets say +10% for active, so 22 gallons. Plus 5% for aggression, which is another gallon or so, equalling 23 gallons.

Is your contention that a tang is fine in a 23 gallon tank, or am I missing something?

I guess what I would "change or add" would be that this is a very vague guideline, and a lot of further research would be needed before stocking your tank.

And I'm sorry, I don't mean to be argumentative. I'm just trying to wrap my head around your system.

Fresh or salt doesn't sound like a correct formula to me!

-10% gallons if sluggish or inactive

1 in.= 5 gallons if fishis bigger than 4 inches

Overall is similar to what I do, but I go from the dimensions of the tanks, verses a general rule like the one you sugest. Also note that an aggressive fish that is 4" might have trouble in a 10.5 gallon tank. The -10% for sluggish, is really not necessary, they would be under the 2"/5g rule. Active fish like the Tangs and the aggressive fish like the Triggers should be housed more on dimensions then tank size, if you ask me. Most of the times both turn pretty close, dimensions and your rules, similar size tanks. If you would like to know more about what I use as rules, send me P.M.

Still makes no since depends on what type setup as well if you have astrong tangk with fish only then that maybe ok but for the most part it depends on how much you feed and as well as what type fish!! Also depends on maintenance schedule that will benefit your tank!!

I think that even with that, a 46 gallon tank is too small for (an 8") Yellow Tang. I think it would be better suited based on the dimensions of the tank. (For an 8" YT, the minimum tank volume based on dimensions, that I would use, is a 67 gallon tank. Thus I would say a 75 standard tank at a minimum.)

Good catch. I did not see that even after looking at it 3 times. It was not until you pointed it out, I saw it.

Yeah, even if the 1 inch per 1 gallon that you wrote is a typo, and you are doing 1 inch per 5 gallon, then 8 inches of tang going into a 46 gallon wouldn't be great. Or do you think that's big enough for a tang?

(8*5=40, plus 10% = 44, plus 5%= 46)

I'm really sorry, I just don't think this stocking tool is successful.
