annoying guppy

1 of my guppies swims around with my 1 male swordtail and tries to nip
at his pectoral fins. at least, i'm guessing this is what he is
doing. at first he used to bother the male swordtail but now he just
sort of ignores the guppy. any idea why this male guppy would be
getting so close to the swordtail's pectoral fins like that? at first
i thought perhaps he wanted a mate and was trying to do something
else, until i got a closer look....

all suggestions welcome!

oh yeah, i have at least 1 more question...

i have 1 male betta in a 1 gallon "aquarium". the last couple of
days, when i check on him after i get home from work, sometimes i see
him flaring. i don't have a mirror or anything that i can think that
may be reflecting his image back at him, so what is the deal? i did
hold a mirror to him twice just to see him flare, but that is it. so,
any idea why he is flaring just out of the blue like this?

You represent food. My Betta does this once and a while also.

Regarding the Betta, my guess would be that he is reacting to
someone/something entering his territory, and is just flaring to remind
you who is boss. I wouldn't think that this is a bad thing.

Regarding the annoying Guppy, removed from their natural habitat (with
more space, shelter, constant foraging, suitable mates, competitors, on
guard against dangers etc), fish substitute other activities to pass the
time away. There isn't always much accuracy in predicting what they will
do and to who. Often they fall into the instinctual pecking dominance,
relentlessly affirming 'boss' alpha status, tormenting all the other
inhabitants (usually ignoring the bottom-feeders who don't fit into the
pecking order unless the fish is a substrate spawner). Sometimes larger
fish which are tormented by a smaller 'alpha' male of a different species
will be confused and let themselves be pushed around. In nature, they
might never meet each other again, so why spend any effort on a
psychopathic Guppy?

In the closed confines of an aquarium, you can influence their behaviour
by adding more fish, different fish, more shelter, re-distributing them
differently through your tanks etc. I don't know if that helps you.
It's just something which happens. You can plan your tanks in advance to
reduce the potential of misfits by having less different species, and
greater numbers in each species (shoalers). That helps by reducing the
chances of 'anti-social' behaviour, and when misfits do occur, they tend
to focus their attention on their own species more, and with more fish
per species, their behaviour gets spread more, making it less
problematic. hth

strange... i noticed again today when i got outta the shower, i
didn't even go near him but i saw him flaring. then when i turned tmy
bedroom light on, he stopped. i just hope he doesn't do this all day
when the light in the room is off because he will totally stress
himself out!!

okay, all of that seems to make sense.

as for the guppy harrassing the swordtail...it just seems to be more
noticable now that my meanie tetras are gone! last night i noticed
them sleeping on the substrate right by each other, so i'm thinking
they are friends but that the guppy just likes to pick on the
swordtail for some reason...
