"This guy should be supported and commended for what He is trying to do. "
and what exactly is that? what EXACTLY is he trying to do. why not just be honest about it.
for instance, if a 10in oscar goes for more than 50 dollars in his area at a LFS, than he is definitely doing the local fish community a service. but if he is selling his oscar for 50 dollars and a "used" 10in oscar is selling for 25-40dollars (like they are in most west coast lfs' that i've seen) then he's doing HIMSELF a service. heck, i just picked up a "used" 12in male jag for 30 bucks from one of my lfs'.....
now, again, there is nothing wrong with that but he should at least be honest about it if that is even a possibility.
and as far as talking about his harships in taking in the fish (medications, food, electricity, etc) those are all things that are complete tax writeoffs if he has taken the time to set up his own business/non-profit and money he would get back at the end of the year if he has done his homework. if he hasn't and jumped into this without the proper research then i don't know what else to say.
as far as the MFK thing i'm not going to comment as i don't know the rules regarding that.
