Brown algae has started creeping all over everything in the tank. Just when I was down to one Oto, I see two and both are very fat and very busily cleaning. They keep the glass spotless, but the plants, gravel, and lace rock may be a bit more than they can handle. I'm cautious about adding more because at $5 a piece (with the mortality rate of 2 out of 5 surviving) they are pretty expensive. I'll probably end up getting some more, but I was wondering what other cleaners do people like out there.
What's your favorite other than Otos?
