Whats this fish?

[Meyer Jordan]

I have 3 guppy that are a little over 2.5" so it is not impossible to grow that large. Especially considering the environment they were in but, like I said in the OP I am only making a guess
PS: Only females will get anywhere close to that size though and not every type of guppy does. Majority of my other guppy are in the range of 1" up to about 2".

How a fish is measured is important. There are three (3) classifications that are used depending on specie: standard, fork and total. For general measurement, standard is usually the norm.

In that case I will add the caveat that mine were going by the total but, obviously we would need to know what the OP is using to measure the fish he found. I dont think "fork" applies at all to my fish though as they have a straight tail. Also I think the OP said the fish was 2.25" which sounds even more like a possible guppy.
PS: Thanks for that chart as I never knew there were so many classifications to measure by

Exactly. That is the reason for posting the chart.

I'm a fisherman,and I don't know anyone who measures or states a fishes measurement as anything other then total length from tip of nose to fork of tail.

I thought that a catch was measured from end to end with 30% added each time the story is told

You are right. Previous post should have said Four (4) length classifications.

Have no idea what this fish may be, but if it is over 2.5 inches in length it is not a Guppy.

It looks a lot more like a guppy than a molly, shape wise. As an FYI, though I'm a koi guy, I've had indoor tanks years back. Female guppies can grow to 2 inches assuming the tank is 20 gallons or larger ... Other than that, it up for grabs ....

Looks like a guppy but I am definitely not the identifier master

I took another look. Still think it's guppy... lol ...

Indeed that is how a real fisherman does it!

Yup! Use a metric ruler and call it inches!

Used that technique alot while a was dating

Not the best photos but it does appear that the Dorsal Fin begins at about the same distance from the gills as the Pectoral fins.On a Guppy, the dorsal fin would begin much further back on the body more in line with the rear of the abdomen.

It was a guesstimate rather than a measurement but it was a total guesstimate if you know what I mean. I will try and catch one again today if I have time. Thank you everyone who has helped so far. I appreciate it.

PS the reason why I guessed was as much to do with the fact that I had caught it to photograph it and put it in a water filled container to photograph it. The fish was not pleased and was thrashing about like mad so I wanted to get it back quickly. I thought it might jump out too. Next time I will put it in a deeper container.

Dinner fork, fish fork, or dessert fork?
