- Eat regularly and swim to the surface quickly at feeding time.
Do fish have brains?
Fish typically have quite small brains relative to body size compared with other vertebrates, typically one-fifteenth the brain mass of a similarly sized bird or mammal. ... There is also an analogous brain structure in cephalopods with well-developed brains, such as octopuses.
Do fish see in color?
Yes they do! In many cases fish color vision is probably comparable to that of humans . ... A very important factor in fish color vision is water depth. Water completely absorbs (or attenuates) different colors of light at different depths, affecting which colors are visible to a fish.
Can I feed my fish at night?
When Should I Feed My Fish? In nature, most fish feed in the early morning and at dusk . Exceptions are herbivores and omnivores that forage throughout the day, and nocturnal species. Although aquarium fish can be fed at any time of day, morning and evening feedings are best.
