Macro ID's please

[Shiandy]

Could someone ID these for me please, and also advise whether they will be ok to keep, or should I take em out, thanks.

I'm refering to the Flower looking (Brown) one in the middle of the photo

1st is Botryocladia

2nd possibly ochtodes

3rd possibly sargassum

I would consider all three to be desireable.

Doesn't Botryocladia have a reputation for rapid growth, kind of like bubble algae? or is it just a myth?

No personal experience with the one pictured. Botryocladia Skottsbergii is considered to be a nuisance it grows much like valonia ( green bubble algae ), and has even been dubbed red valonia.
