Fish

Dudley Moore's character, Arthur, once discussed fish with his butler. He made the comment that 'fish all bathe together. Of course, they also have the tendency to eat one another. Do you think fish ever get tired of eating seafood?'. Which, to me, is extremely funny. It has also led me to wonder about a few other fishy topics.

Fish swim in their own waste. At least in tanks and so on. Those filters can't take care of it all, right? Hence the need to clean the tank every so often. Here's my ponder: people who swim in their own waste tend to become ill. Violently so, in fact. So, are fish naturally immune to their own wastes? Does fish waste not contain bacteria? If it does, is it bad for fish only or would we humans be poisoned also? And, when humans become ill, we get things like hives, diarrhea, and vomiting. I have never seen a fish with hives. I've never seen a fish with the shits. Nor have I ever seen one puke. However, I've never seen an owl puke either, but my community college science professor had us dissecting owl pellets, which he assured us were actually a form of owl vomit, so I'm fairly sure they do it. That being the case, isn't it reasonable to assume that some, maybe not all, fish vomit. Maybe the reason I've never seen one do it is because I've only seen fish in tanks. With all that glass around, even with plants and little sunken ships to hide in, maybe they are too embarrassed to vomit in public.

Just pondering.
