If a person buys a clownfish for $1 they probably aren't going to want to shell out for the best food and environment. However if that clownfish costs $50+, then $20 for the better food for a month doesn't seem so bad. Also I don't think the poor should have pets. It's less of an issue in the aquarium hobby, but if the pet gets sick they don't have the means to take care of it. Also chances are they don't have the means to give them optimal care. Now middle class and up has disposable income. As such if they really want that Gem tang they will find a way to afford it whether savings, credit card, or some other method is involved. This will be true if the prices rise on something like a clownfish.I can see that side of the argument, yes. However, it very well could turn this hobby into a 1% one meaning only a few can actually afford it. Few fish are already there then let us take a look at the designer corals that someone slaps a fancy sticker on then adds a couple digits to the price tag. Don't get me wrong I know it is about choices and I'm just has guilty with my many vices. Just trying to separate out the conscientious aquarist (after all Fenner wrote a great book on it) who is doing the right thing suddenly getting thrown out of a hobby due to a increase in animal life. I consider it collateral damage and I hate to see those people get caught up in this.
As with life there are many factors in play here many of which most of us will never know. I personally just try to do the right thing and treat all my animals has family pets. I know it sounds silly but it keeps me honest at least.
