水草情迷

新手設缸約一個月。D草冇乜大問題。但發現水中有些好細好細，白色會動，好似識跳嘅嘢。不過要好細心先見到。唔知係乜呢？
另外重有D唔知係咪白線蟲。約1cm, 好幼。平時唔多見到，但若關過濾2小時再開就見到一定數量，跟住又冇咗。
請問依D係咪好平常？還是要盡快處理？
有時都見到條飛狐好似食緊嘢(唔係藻)，唔知係咪食緊依D生物呢？Thank You!

Don't worry ! No big deal.Your fish will help you (if you have).

My SAE sometimes will attack baby shrimps too !

Thanks! So I don't need to worry la.
