HELLO
The day of the redo is nearly here.........the clock is ticking.........but time is running out..........
I'm thinking of what fish(or other creature) can serve as a janitor of my 20 gallon community tank. I'm thinking plecos, but I learned that they are more of a pest than of help so kick the pleco off the list.

I'm also thinking of otocinclus catfishes(ottos) but it seems that there isn't any in the stores. What other water creatures are capable of cleaning algae and other dirt in my tank?
THANKS IN ADVANCE!
