Nothobranchius furzeri is one of the most tricky Nothos. It is aggressive, canibalistic, very short lived, and the eggs develop unpredictably.
Because this fish lives such a short time (3-9 months) it grows quickly, needing a lot of food. Failure to provide it will result in the largest fish eating some of the others
Eggs develop far less uniformly than other nothos; usually some will develop almost immediately (2 weeks), with the others taking anything up to 6 months (or even longer under specific storage conditions)
Both red and yellow phases exist, with some populations throwing up mixed hatches. There were interesting behavioural differences in the mixed fry, with the reds showing considerably more aggression than the yellows
