I'm about to get my 1st afro's. How much current can they take? I was thinking about putting them in my 125G BB pleco grow out tank with a lot of driftwood and caves. I currently have a strong current in a bottom corner of the tank for the 17 baby pleco's to play in (they love it). The driftwood brakes up the 1000 gph current some but I don't know if it would be too much for baby afro's. My other tanks have sand or gravel. Thanks for any help.
