Slanting Vallisneria

[nagukush]

Hi Friends !

I find that some of my Vals have slightly tilted and are growing a little slantingly. Is this ok and can I let them grwo like this ? They look natural this way, but just wanted to know if its essential to straighten them up again ?

Kindly let me know...
Thanks and Regards
Kush
