How often should I feed my fish?

This is of course the million dollar question. Fish are by nature opportunistic feeders. Meaning that they will feed on whatever they can find. There is no clear cut answer here. A general guideline for feeding flakes and pellets is feed as much as your fish will eat in 2-3 minutes. The key is to feed little but often. This is not only very important for the digestion of fish but also allows the filter to cope easily with any uneaten or undigested food. Wafers on the other hand take longer to be consumed and algae can be grazed upon all day.

Some fish like eating vegetable, is this true?

Correct. Even the more omnivore cichlids will eat some veggies. The key here is to present and prepare the vegetable the right way. Spinach or salad leaves need to be blanched before being placed in your tank. Blanching consist of rinsing under hot water. This process will break the cell walls to allow better digestion. Our Seaweed range offers you versatility and variety all in one. To avoid algae or spinach leaves clogging up filters or overflow pipes we strongly recommend using our seaweed or grid feeding clips. ‘Vegetarian’ fish will graze all day and will feed whenever they want.
