I purchased a small group,of BN plecs today at a club auction and must admit I am not a bristlenose keeper with any experience. I am basically a livebearer person with no experience to speak of in the bristlenose arena. I have seen reference to people who keep BNs having driftwood. Is this something that a BN actually needs or is i an option that is often given a new BN? I want to do right by my new fish but I am sure that I do not have the knowledge I should have in terms of their needs. Right now I am prepared to give them things like spirulina sticks, which I would expect them to need, but I am concerned because there is no driftwood in their tank. Is this something I need to add for their health or is it an optional item only needed for breeding purposes?
