When it comes to optimal feeding frequency most aquarists will agree that two to three distributions per day , with each distribution not exceeding 3-4 minutes is a solid schedule to go by. This of course with the exception of some species that have a way to go longer without food. Generally, small fish are fed more often than larger ones, but in smaller amounts of three or four small portions which is better than a large one.
Commercial foods are generally very good. It is therefore necessary to avoid over-feeding because an excess will not be completely eaten by the fish and will pollute the water and make it dirty.
By observing the behavior and the habits of fish, we come to the conclusion that we know their needs.
Some tips to feed optimally
– observe the behavior of your fish, do they eat on the surface or in depths where they spend most of their time?
– in the entire aquarium, it may be necessary to use different types of food according to the different species (example: one that floats and one that flows)
– many species require an additional feeding after their bedtime
– observe fish to see if all of them are able to get a share: equal access to food is not really possible due to some being more aggressive than others but it should be good enough.
– fish are cold-blooded animals which means that compared to warm-blooded animals, their dietary needs are comparatively different as food is not used to produce heat (they are know to not need it. Since the temperature of their body fluctuates as a function of the outside temperature.
– fish increase the speed of their metabolism as temperatures go up. The goldfish, for example, will need higher energy intake if the water is 20 Celsius than at 15 Celsius.
If you want to automate the entire process of feeding them then get an automatic fish feeder like the ones here www.bestautomaticfishfeeders.com. They will help you if you go on vacation or out of the house for long periods of time.
