Light Trap

[<colingorton@eurosport.com>]

It wasn’t until a couple of days ago that I
realised why, with the addition of MH lighting, all
my fish seemed to start breeding! I’d heard of
all sorts of breeding stimuli, but never MH lighting.
Anyway it was only when I was in the fish room quite
late that I realised that the MH lights are
attracting more night-flying insects, the get too
close to the lights a quick ZAP and they’re
floating in the waterJ. Even quite big insects like
Ichneumon wasps seem to be no problem for my intrepid
fish. Some of the bigger ones escape, but most are
tackled bit by bit. This behaviour has also helped me
to realise why so many fish will take food into their
mouths, chew, spit, chew, spit chew and then finally
swallow their food. I think it’s a sort of
“de-husking” thing, like the way people
who don’t have machines toss grain into the air
to separate the grain from the chaff. Maybe this
behaviour also helps to break the carapace to get at
the juices inside.
Anyway, as a result of this night-time feeding the
fish aren’t nearly so greedy during the day, so
I’m cutting back on their day-time feeds. I
think the MHs may even be saving me money!
