I was talking the other day with a friend about getting a tank a Xmas gift
but then we got into hazards which I didn't want to be liable for. He
mentioned from skin to respiratory issues.

I know is silly but I have to ask. I'm not giving up my tank but got
concerns about my kids.

I believe most marine organism would die out water, but you know better
than me. I'm talking about the standard raw tank without those UV filters.

What are the chances of people getting diseases/parasites from a fish tank
since we are kind of breeding them in a closed enviroment, and what are we
more expose to?.

TIA
