How to measure a fish?

[jackdaniel]

I can't seem to find an existing post on this, but I'm sure someone must have asked it before:

"What's the best way to measure the length of a fish?"

More specifically, short of netting it and pinning it next to a ruler, what's the most human and efficient way to measure a fish in a tank?

I would think I could take a picture of the fish up against the glass and, with known tank dimensions, estimate the length by comparison. Are there any other tried-and-true methods?

Thanks!

Wrong section...

But what you can always do is set an object that has a know size against the tank and snap a picture when the fish swims by. That will give you a known reference and from there you estimate.

One of the best ways I know of short of netting the fish .

yup for accuracy its netting
for estimations compare it to stuff in your tank

Or stick a ruler on the tank, and wait for it to swim by/stand next to it

Just wondering which section this should be in if not here?

Stick a ruler, estimate and round it off. Unless you want every single millimeter then good luck.

first net the fish and hold out your hand to keep it from jumping (still in the net)
the quickly have a friend come and measure it

i sit with the tape measure out and throw in a few pellets then i get a pretty good approximation of size as they swim the length of the tank and i hold the tape measure up.
i wont take a fish out of the water, like some do, just to measure it. thats just cruel and unnecessary.
i am going to measure my fish when i move house when they are out of the tank and being transferred to their mobile home.
