 Brachydanio Rerio (Zebra Danio) - FishandTips.com
Danios, usually swim near the water surface and are notorious jumpers.
Zebra danios can bring a lot of life in community tanks, however it is strongly recommended to have them in a separate tank if trying to breed them.
Spawning should have taken place early in the morning and the non-sticky eggs are scattered in between the marble so the parents can't reach and eat them (some hobbyists use mesh to cover the lower part of their tank to replace the marbles).

 Caring for Zebra Danios, by Peter McKane
Even though the zebra danio is a common fish, regularly found in tropical community tanks world wide, they do require something of a caring touch to make sure that they are both happy and healthy.
Zebra danios are not prone to any particular disease, and because of their active nature they are seldom affected by ich, due to the fact that they will brush off the fungus in their everyday activity of passing by stones or plants in your tank.
Knowing that zebra danios need to be kept in schools, preferably away from fish with fancy tails or fins, you can expect to have absolutely not problem with the fish in a community tank.

 Heredity - Evolution of danio pigment pattern development
rerio pigment pattern metamorphosis is characterized by a segregation of distinct populations of cells, with most of the adult striped pattern comprising newly differentiating metamorphic melanophores and only a small contribution arising from the reorganization of embryonic/early larval melanophores.
rerio, there is no evidence for an interspecific difference in the activity of the locus in question; but if the mutant hybrid differs from the wild-type hybrid, this raises the possibility that the same gene or pathway affected in the mutant also differs in its activity between species.
Studies of danio pigment patterns are beginning to reveal basic mechanisms of pigment cell differentiation and morphogenesis during the development of adult form, and how changes in these mechanisms can generate pattern variation within and among species.

Most danio fry emerge large enough to eat finely crushed flake food or you could even try that commercial fry food(i've never tried it and i would be iffy about using it, just crush your flakes).

 Zebra Danio Profile
Almost any tap water (once dechlorinated and dechloraminated) will suffice for CBB D. rerio but acclimation processes should be used if your water's pH or hardness lie outside the given ranges or differ greatly from that in which they were kept at the LFS.
If comparing two wild-type D. rerio of opposite sexes, the background will be more golden on a male and a paler yellow on a female.
Their ease of breeding and genetic morphological variability are often cited by scientists as reasons to keep them handy in the lab.

Like other danios it is omnivorous and a peaceful fish that gets along well with other fish in community tanks.
Zebra Danios serve as a common and useful model organism for studies of vertebrate development, because it reproduces very easily, passing from the egg to the larvae stage in less than three days.

 BioMed Central | Full text | Identification of multiple integrin beta1 homologs in zebrafish (Danio rerio)
Despite the fact that the zebrafish (Danio rerio) is a rapidly emerging model organism of choice for developmental biology and for models of human disease, little is currently known about β1 integrin sequences and functions in this organism.
The complete amino acid sequence of human β1 [Swiss-Prot: P05556] was used to probe the Danio rerio genome ([59,61]) using TBLASTN [53] to identify genes with highest sequence identity to human β1.
The β1 integrin sequences identified in Danio rerio were aligned with the human β1 sequence [Swiss-Prot: P05556] and the ancestral β1-like gene previously identified in Ciona intestinalis (JGI Ciona v1.0 ci0100141446) [8] using CLUSTAL X [54].
