Does anyone know what plant this is?

My first guess was Lobelia cardinalis, but looking at it longer Im not so sure now. Was it in a tank when you bought it?

@CassCats @connorlindeman
Any ideas?

I think its lobelia too I've never seen them do well as a strictly aquatic plant

That does look like Cardinal Plant. It will transition. You won't keep those purple leaves.
It will end up more like this.

Yeah looks lobelia to me too

I bought it from PetSmart. It didn't have a name tag with it, so I don't know what it is.

I am worrying too about how to keep those purple leaves.

It grows purple like that when it's emersed, I had no idea it transitioned when submerged learned something new today

Purple waffle. it's a garden plant and needs to be out of water otherwise it will be dead in a week.

I was hoping it wasnt purple waffle. It does look very similar to cardinal plant.

Sort of looks like Water Sprite . Ceratopteris thallictroides .

It looks nothing like any cardinal plant i've owned emersed or submsersed. Purple waffle sounds right.
