Hello ladies and gentlemen,

There's this thing growing on my blasto. It looks like little bubbles. The color is tan. Is this some kind of algae?

No the bubbles seem to be independent of each other. I think they may be multiplying.

Bubble algae is usually green but can take on that gold-ish color. Run a google search for it and see if it resembles what you have in your tank.
