I have spent the last month setting up another 6x2x2ft planted tank for my gf that was supposed to be getting a bunch of apistos & two plecs. I have just been informed that she has changed her mind & has ordered 5 Geophagus Rio Branco that will be arriving tommorow. I'm fairly sure I know the answer already, but will the plants be okay if I surround the bases with large river pebbles? I have done searches on this fish but can't find any info on them other than they get to about 28cm. Should I move the plants out while I have the chance & decorate with wood & rock? I'm rather skeptical that plants can survive with 28cm fish digging around all the time.
