Jelly Bean Tetra - Ladigesia roloffi - Federation of British Aquatic ...

Some report it to be a little pugnacious but generally it is a good community
fish. Water conditions are not particularly critical and some algae in the
tank may be appreciated.
Although often described as laying its eggs in a pit in the substrate, it also
spawns amongst plants where the sticky eggs soon get attached to the
leaves of any feathery-leaved plant such as Java Moss, Vesicularia
dubyana, or Myriophyllum. The eggs take around a week to ten days to
hatch (time varies with temperature) and the parents guard the brood to
some extent. Raise the fry with the usual micro-foods and newly-hatched
Brine Shrimp at first before gradually increasing the food particle size.
A more recognisable Killifish is the
Bluefin, Lucania goodei. Reaching
60mm, this fish is also a native to
Florida and neighbouring Georgia.
The male has an orange-based
bright blue dorsal fin and red caudal
fin. The female has plain fins but
both fish show a dark zig-zagging
dark line along the flanks, that of the
male is more accentuated.
This is another plant spawner but is said to a trifle delicate and not like
being moved around too much, nor to have too warm a temperature.
Just as decorative is the Red
Shiner, Cyprinella lutrensis.
It reaches 80mm and has
stunning colouration especially
when breeding. The male is
violet with bright red fins and
develops breeding tubercles
on the head and pelvic fins
when in season.
Again, this is a cooler water fish. This species is widely distributed on the
central plains area of Northern America, from Illinois down to Texas.
