What exactly do Plecos do? Someone I know has a few and I **might** end up taking one because of some circumnstances she has, so I was just wondering if it would do more harm than good in my 5 gal.
Keep in mind, I DO two weekly changes.
Now, I don't exactly know what kind they are, all I know is that it;s NOT one of the giant ones. They're small (about betta size or smaller) with rather round heads (like, really round).
Any help with this?
She doesn't want to return them so I suggested taking one if worst comes to worst, so I want to be prepared in case it does happen. :/
