People with custom aquariums tend to make the same mistakes as any other novice fish owner.
The most common of these is overfeeding.
The owner will take time setting up the perfect fish tank.
They will check the water quality, add the correct materials to provide sanctuary, plants for food and decoration and also have the right heaters and filters.
They will spend time on selecting the different species of fish and yet they may not take time to educate themselves on these fishes feeding habits.
There are three main types of food for fishes being natural, cultured and manufactured.
Natural foods for fish kept in custom aquariums include blood worms, glass worms, gnat and mosquito larva etc.
Some aquarists believe that the physical activity of catching live food is beneficial for fish kept in captivity.
You have to be careful where you source this food as you do not want to inadvertently add toxins to your fish tank.
Also be careful when feeding worms to fish.
Glass worms are fine for adult fish but if you have very young fry you may find the worms attack them.
Cultured foods are those that you or the pet store owner raises as a supply of food.
It has to be said that most women will not like you raising live animal foods in their kitchen.
Some forms of vegetarian food can be introduced into custom aquariums such as chopped lettuce and green peas.
Manufactured foods are probably the easiest way to feed fish.
It comes in the form of pellets or fish flakes.
Be aware that some bottom hugging fish will need pellet food as the flakes won't reach the bottom of the tank before being eaten by other inhabitants.
Don't be tempted to add in too much as overfeeding fish is a common cause of pollution in custom aquariums.
