Hi Guys,
So I like to jump on yahoo answers every once in a while, to check out the goldfish and axolotl questions. Yesterday a guy asked about substrate. He did not want a bare bottom, gravel, or sand. I wrote that I use river rock pebbles that are just large enough that my fish can't suck them up. I also said I use enough to cover 50% of the floor, but spread out evenly so that they can root around, but not have anaerobic pockets.
Another answerer sent me an email saying that I am propagating animal cruelty and should be banned from Yahoo. He said my rocks will rip their fins and that I am killing them with hydrogen sulfide (I thought sand was the major culprit). He goes on to say that he sponsors the blah blah goldfish show in Blah blah and he is the authority on goldfish keeping. He thinks I should be ashamed of myself.
Any thoughts? The paranoid/OCD part of me is afraid I am doing something horribly wrong here. I was so shocked to read his email, especially because we usually give just about the same answers.
