Almost Right

You gotta love it when customers know things...but they're only partially right in their knowledge.

I had a customer today who wanted to buy like three or four fish.
Like goldfish.
And put it in a 3.5 gallon tank. 

Why?
Because they thought the rule with fish was one fish per gallon of tank.

Which is close.
But not quite the rule.

The rule is one inch of fish equals one gallon of water.

Meaning that if a fish grows to be two inches it's gonna need to gallons of your tank.

So with a 3.5 gallon tank.
You have 3.5 inches of fish.

And if the customer was looking to get like guppies or neon tetras....then they could get three or four fish that way.

But goldfish?

The rule of goldfish is that they need two gallons of water for every inch they get.
Because goldfish are a messy fish in that they give off a lot more ammonia. 
So they need more water.
Plus like...they can get ten inches full grown.
so a single goldfish would really need like a 20 gallon tank by itself. 

And the customer wanted to put four of them into a 3.5 gallon tank.

*exhales*

Yah...that was a fun circular conversation to deal with.
