Does anyone know the plant?

hi!
today what concerns me is that I've had this plant for quite a few years in most of my tanks now and I don't know what it is,, it grows with 5 leaves arranged in a 5 point star-like pattern but is really lanky and thin, also it seems to be a stem plant and it gets its tips red when growing in direct sunlight (like in an outdoor mini pond), it kinda looks like a thin stretched out rotala

Can you post a picture? That would help a lot.

It looks like Elodea Canadensis to me.

either elodea or hydrilla.

the small floating plant looks like salvinnia

big floating plant looks like water lettuce

Doesn't look to be an elodea, looks a bit more similar to some hydrilla species

Go with that then, you have the plant we are just looking at photos.
