Please help

I found this on the market, and based on the vendor, they cultured this kind of sea grapes, but to me it looks quite big for sea grapes. (3-5mm in diameter)

can I put this in my tank?

tank is 6 weeks old, 75 gallon and completely cycled.

i only have two clown fish currently.

ps. it looks really cool that is why I'm seriously wanting it to be on my tank.

You technically could, during the day they release co2 but at night they absorb it causing ph to fluctuate. In such a large tank with only to fish it probably would be fine though.
