My recent batch of betta bulbs seems like it will be a dud all the way around, and so I'm considering buying already grown plants from my local pet store. What concerns me is that they keep their plants spread out throughout their tanks.
One plant may be with their new guppies, another might be in with their goldfish. Can plants that are kept this way transmit diseases among fish? If I buy these plants should I quarantine them, and if so how will I know when it is safe to introduce them to my sorority?
