For these fish to breed, it is necessary to get them in top shape in order to survive the often-violent spawning process and to rear the strongest fry with the best chance of survival. One of the very first steps in conditioning bettas for breeding is to get them on a diet of live and frozen foods.or these fish to breed, it is necessary to get them in top shape in order to survive the often-violent spawning process and to rear the strongest fry with the best chance of survival.

Zinc oxide is the only single active ingredient allowed here in the US that offers full UVA and UVB protection. See chart below. Critical Wavelength and UVA Protection. The critical wavelength is the wavelength at which the sunscreen allows 10% of the rays to penetrate.A sunscreen with a critical wavelength over 370nm is considered by the FDA to provide excellent UVA protection.Badger sunscreens have critical wavelengths ranging from 379nm to 383nm, offering excellent protection from UVA rays!inc oxide is the only single active ingredient allowed here in the US that offers full UVA and UVB protection.

The critical angle of reflection is another key concept in the study of light refraction and is illustrated below in Figure 4. When light passes through a medium of high refractive index into a medium of lower refractive index, the incident angle of the light waves becomes an important factor.
