Black hole

[Fish rookie 07]

I’ve just got a new clownfish about 1.5cm long he’s very active and a strong swimmer for his size but my output hole is rather large...
He’s been alright over night but for long term do I need netting or something?...

Is that the return from your pump? If so, will be fine.
