Though guppies are thought to be the easiest fish to keep,
large show guppies had become one of the most
challenging fish you could keep in the hobby. The exaggerated
finnage and many generations of careful, protective,
clean environments led to fish that required bare bottom
tanks, no plants and the routine addition of salt to do their
best. When a pair was given to a fellow aquarist, who then
put them in a standard planted tank with gravel, the fish
often did not last very long.
These purple deltas offered were begun with top quality show
stock that was purchased by another hobbyist from the
original breeders a few years ago. Over time, an effort to
produce a beautiful, hardy blue delta evolved into the line
offered at this site.
Due to fin nipping, as is the case with any long-finned
species, they should be kept in a species only tank, or with
tankmates that you know will not bother them. With their long
finnage, they move unnaturally in a movement
other fish often interpret as their being wounded or
otherwise vulnerable, as well as carrying finnage that is too
tempting for many fish to pass up.
They require moderate to strong aeration in a tank that is
well filtered with some water movement. They also do best
in smaller sized tanks. Many breeders routinely keep them in
2.5 and 5 gallon tanks. Here, they are all kept in 10 gallon
tanks. A simple 5 gallon tank with a box filter, light and
heater is adequate.
All guppies benefit from live or frozen shrimp, but these
fish especially need the advantage that brine shrimp provides.
Full, beautiful tails require a strong body that dry food
alone generally does not provide.
Females are removed to have their fry into another tank
filled with 1-2 week old fry, then remove her as soon as she
drops, or allowed to drop into a tank of her own with Java
moss. Feed fry BBS (baby brine shrimp) every day for at least
the first week for best results, making sure to keep up the
water quality. Change water in the fry tank often. Most will
separate sexes when a gonopodium or gravid spot can first be
seen at about 3-4 weeks, and the sexes are then raised
separetely. At 3-4 mos., breeders are then chosen for the
next generation based on traits you are looking for.
Fry tank should be warmer than the adult tank, at around
