	How many Ottos versus tank size.....
dreamweaver8891 Big Fish Posts: 320 Kudos: 533 Votes: 79 Registered: 25-Apr-2004	Is there any general rule - and note, I did say general - to determine how many Ottos would be needed versus size of aquarium... I realize through other threads that Ottos are schooling fish - and I also understand that water conditions, algae production, etc. will vary from tank to tank..... But what I haven't read about is under average aquarium conditions, how does one determine the quantity needed? A 10 gal certainly wouldn't need as many as a 20 gal or 55 gal to control algae ---- Or does size of tank matter? To thine own self be true...

I myself kept 6 in a 29 gallon for over 6 months with no problems. The one thing I always suggest when purchasing ottos, is to make sure your tank is really covered in algae before adding them. Most ottos are pretty much starving to death when purchased at the stores.
