Best Food for your Tropical Fish 

You love your fish and always want to give them the best food they can have. But the only way for you to know whether the food you are giving is good or not is to perform testing. That’s correct, but the problem lies when you give them the wrong food first, and it eventually ruins the whole aquarium. Just because you see they are gobbling up the food does not actually means those are good for them.

So how do you know upfront about the nutrition fact of your food? Well, you have to figure out the ingredients that are in that food first. To be more specific, you have to know about all the vital vitamins and supplements that are good for the overall nutrition of your tropical fish.

Vitamins & Other Essential Supplements

Now, let’s consider about the Vitamin D first, which is known to be one of the most recommended vitamins in case of feeding your tropical fish. Essential amount of this vitamin, as well as other vitamins, can provide the food with an abundance of nutrition. However, a properly blended food which contains all necessary ingredients including proteins, carbohydrates, minerals, and iron can also ensure the presence of all vital vitamins in your food.

Okay, now you know about all the vital ingredients that are necessary to ensure your food’s nutrition. But another way for you to know which special type of food or “brand” would impact more on your fish is to ask the store manager. They can give you a practical recommendation in case of selecting the right food for your tropical fish.

Taste Buds & Occasional Treats for your Fish!

Now, do you remember on the beginning where I talked about “taste buds”? Yes. Our fish also have their own “taste buds” just like us. And, just because your fish are absorbing all the food doesn’t mean they are good for their health. You can, for an experiment, throw some small piece of bread on the aquarium and see their reaction. They will probably gobble all the pieces eventually but they are certainly not good for their health.

What most of us usually get it wrong is, just because they are eating them doesn’t mean they are palatable. Or let’s assume they taste good for the fish, but if the food is not completely balanced, you are definitely giving them the wrong kind. So now we can conclude that your food should be both balanced and palatable. You can also take recommendations this time from the store manager and taste it for a few days to ascertain whether your fish likes it or not.


Now, I can assume, you have got an effective strategy and knowledge to find out the best possible food for your tropical fish. But do you know the type of fish you have on your aquarium also determines the kind of food you should provide? Well, that’s the last thing you definitely should consider.

If you have a diversified kind of catfish in your aquarium and some of them are vegetarian kinds, you can apply Spirulina with your food. Spirulina is a blue-green kind of algae that you can buy reasonably from most of the pet stores. They are basically a small sinking round tablet for your vegetarian fish. Drop one or two in the aquarium and let them sink to the bottom. Your fish will eventually consume them.

Some dried live foods that contain krill and bloodworms can also do well as occasional food for your tropical fish. The brine shrimp, also known as an ice-cream for your tropical fish, gives them a palatable experience. The integrated application of all these foods with spirulina will definitely ensure a balanced and proper diet for your tropical fish.

Secret “Power-Supplements” for your Fish!

Now you have come into the most exciting part, the “power-supplements”. Yes! Just like some of us take supplements for transforming our body in a short time. But in that case, both aesthetic and growing indications you can consider for your tropical fish.

To experiment it successfully, you can buy some inexpensive fish and store them into a separate aquarium. Now, apply some new branded supplements and test the results. You can also change the food after a relevant time and apply a different type of food in terms of their brand name and contained ingredients.

This way, you can actually figure out your own invented “power-supplement” for your tropical fish and apply them to bring in a new change for your overall aquarium. Now, the next part of this guide will cover “How to feed your tropical fish, like an expert”. You can take notes which you’ll find crucial while applying.
