Help in identifying a strange fish.

[bluesilver]

I've been keeping an aquarium for about a month now, and my tank community consists of...

-8 guppies (6 male, 2 female)
-10 neon+cardinal tetras
-8 pink zebra danios
-2 golden tetras
-2 penguin tetras
-2 purple harlequin rasboras
-2 red cherry shrimps
-10 sunkist shrimps

and then there's this fish...

The photograph attached to this post may not be too helpful, but the key features are that it has 1 anal fun and 2 dorsal fins, which is in characteristic of the the other fishes in my tank community. Therefore, I don't think it's their offspring.

Can anyone help to identify this fish? How do you think it got into my tank? Will it grow to become a predatory fish?

Im not sure if it's just me but I don't see any photographs. Maybe you can try uploading again?

Need a photo, but if I would hazard a guess, if you have live plants, it came from a fish egg that hatched successfully in your tank. The egg came attached to the plants, which happens if they are grown in ponds that contain fish, especially in some plant farms here.
