A little Help IDing

[joshsteph2004]

Hey All, It has been awhile since I have updated anything on here, but I think my tank is finally running real good. I went on a 2 month patrol on my ship and I came back to a tank filled with all new types of stuff growning and I can not ID some of it. A little help will e much appreciated.

First one is some kind of red bubble algea.

The second two look like small sponges (cotton ball or something?).

First is a red algae of some sort, looks a lot like a Botryocladia sp. Do a search on that and I bet it looks pretty close to what you have.

the first picture is a macro algae. keep an eye on it.. but im guessing it will grow pretty slow.

2nd is sponge

The red buble algae can spread, but in my experience is not nearly as invassive as the green bubble algae (Valonia). I tryed to ID my green bubble algae a while back and was shocked to find out how many different species and even genuses of bubble algae there are. How some of these can be differentiated I'll never know.
