Lol. I'll start that as soon as I can. If it shows what I get to witness, I had one nerite hit a Cory with his shell and poke another one in the eye with his feeler. The inca snail found a wafer the other day and nearly flipped over with the goodness of his crack algae. The other nerite is smaller and never gets anything other than the inca trying to crawl over it somehow.
There is no such thing as an expert. Only more experienced than others.
