New tank...new albino bristlenose pleco...not well
My husbands albino bristlenose pleco started turning red, from his 'nose' onto his 'tummy'. It's a still rather new tank (started 30th Dec 2020). My husband bought the pleco (Geoffrey) two weeks ago. All was fine until yesterday. My son has a mature tank and his pleco is absolutely fine. I tired to attach few photos. It looks like Geoffrey scraped his 'tummy', but I'm not sure if that's the case.
I would be grateful for any advice.
