I have 4 peppered corys and 2 otos but those are mainly scavengers and aren't doing much in cleaning up my algae problem (blue-green algae). I saw some Golden AE at the LFS yesterday and they were really working over an algae covered piece of driftwood. From what I have read, I am afraid to put one in my 29 gallon tank as it seems that they get agressive as they get older. I don't want to get something I'll have to get rid of later. I'm sure someone here has experience with them. Thanks in advance for your help.
