Hi. I just transferred my guppies and all their stuff and my Cryptocoryne Wendtii to a new, bigger tank. A few minutes ago, I saw one of my guppies, Tobias, picking at the roots of one of the Crypt plants. I guess I didn't see when I was putting it in the tank that some of the roots (just a little bit) were exposed when I stopped covering them with gravel. Is Tobias safe?
