i'm having a little bit of an algae problem and i wanted to get something to suck it off, so i was wandering if anybody new of a good and cheap pleco that i could get. my price rang is about $8. thanks!
You could buy some live plants which would help because they compete with the algae for nutrients in the water.
If you wanted a pleco a good basic one is the bristlenose pleco, or, you could buy a group of otocinclus. I think the oto's need/like a group of six and the bristlenose can be on it's own.
Both of these species need driftwood in their tank as they like to munch on it and it helps keep them healthy!
Hope this helps!
