In case you didn't know, fish are pretty dumb. The guppies we use in the lab have this tendency to go towards the siphon and touch it with their little fish faces and then every so often one gets a little too close and gets up in the siphon, which can lead to fishy demise. Sometimes they swim out, but mostly it's up to me to save their tiny fish asses. I'm a god to them. A god.
