How to keep marine algae/plant

[Underwater]

Is it possible to continue growing marine algae/plant in our home tank? Those look like green grapes, red bamboo and fern leaves? Pls advise. Tks.

My tank has no tangs or angels.

Not advisable as they require some nutrients from tap water to thrive. Usually we put them in the sump tank to absorb nutrients so that algae doesnt grow in our main tank. U wanna do the opposite LOL

actually i find them look pretty nice in my main tank...like a planted tank with corals. just that i got to forgo having fishes like tangs and angels..

You can grow them in your tank, why not? Addition of plant food and iron would be required. But be aware of the fern like caulerpa, they can kill corals. But for display tank, I would suggest the red plants (with bits of grapes on its branches). They look nice in a reef aquarium. Be sure to harvest some when they overgrown. Either throw away or use it to feed herbivore fishes from other tank if you have.
