Bubble algea and fish question

[Lionfishy]

Hi all,

I have a 25g tank (Fish only) with 1 true p. clown and a splendid dotiback (around 3"). The dotiback is aggresive and is the boss over the rocks in the tank.

I am wanting to add 1 more fish in the tank and i am not shure what fish to add. (Thinking a Coral beauty Angel) but they like the rocks and so does my dotiback so i am guessing it is a bad idea to put the together.

I am wanting to and a fish into the tank that likes to swim around more that hide around the rocks.

Qestion 2

I also noticed green/blue "stuff" on my live rock and it is hard but if you press on it, it can POP. I think that it is Bubble algea.

Is it bad to have in a tank?
Will it hurt the fish?

Thanks,
Lionfishy

Not sure about the first question but we have bubble algea as well. We removed ours with tweezers but you don't really want it to pop in your tank.

Some fish will eat the bubble algea but if you don't control it can really get our of control.

Good Luck.
