Anyone else ever hear of this?
"Dear Dr Ghoti:
Maybe I should ask The Psychic Fish about this but here goes. Late at night I sometimes hear a strange and alarming "clinking" sound while I am working on my computer. It sounds as if someone (or something) has tapped my Betta bowl with a spoon. Can you think of any explanation for this?
- Andrea, Tukwilla"
Dear Andrea:
The Betta is doing it. Sometimes they get bored and suck on an air-bubble for entertainment. If they are especially talented they can create enough of a vacuum to cause a slight clicking sound which may be amplified by the glass container. Sound travels faster underwater than in air and....well...that has something to do with it, but I can’t remember.
