Aquaman

How long does it take to catch a few fish?Answer: if they're speed-of-light tetras, just how long have you got? Aquaman eventually told me to head back upstairs and have a seat for a while!
Anyway, it's just as well they're zippy because one of the other fish in their new tank has decided to be nippy. Not sure why, it hasn't bothered other fish before. Tetra wars.
