Underwater caterpillar?...

I'm not even sure where to put this thread.
I found what couldn't be anything but a caterpillar, sitting on a piece of plant floating around my aquarium.

What?

 

Looks like a grub

 

Oh? What are they exactly?

 

A grub is a land bug that usually turns into a kind of Beatle. Kind of like a caterpillar turns into a butterfly or moth. I don't know if that's what it is for sure but it does look like one. Maybe it fell in?

 

Interesting, well thanks. Can I feed it to my fish?

 

If its small enough, I wouldn't think there's any harm in trying to feed it to the fish. Was the grub in the water or just floating on top?

 

I have no idea honestly but I don't know why not.

 

It was in the water on a small piece of plant that was resting in the tank

 

It is a caterpillar . You can tell it has the suction cup legs in the second pic. Grubs just have little claws, and also tend to be buried underground not climbing on leaves. It most likely fell in the tank with the leaf.
Personally I wouldn't feed it to my fish. No idea what it's got in its gut. Just throw it outside.

 

I agree with aich could have parasites or a infection of some sort

 

where is that leave come from in the first place? is it outdoor tank?

 

It's actually a piece of plant, not a whole leaf. I think a piece of Java Fern that got knocked around when I went to prune the Java fern's dead leaves today.

No idea how a caterpillar got in there, this is my tank in my bedroom on the second floor, but it was just sitting on the plant piece, likely munching away, completely underwater.

If you were a grub stuck in a fish tank I bet you'd climb on to a leaf

Not that it matters which it is but grubs have the little claws on the front part of their body only

 

Well whatever it is I put it outside haha

That's my point Lucy. Grubs don't have those sucker feet, at all. That's a trait of a caterpillar. They (grubs) have 3 sets of claw legs at the front, and that's it.

Grubs also tend to come only in dull white and beige with brown spots, due to their subterranean life. Some grub species have no legs at all, but grubs never have legs on the abdominal section of the body.

Edit: not that it really matters, I just used to do entomology judging back in high school, and this stuff is ingrained in my head.
