Paradise Fish (Macropodus Opercularis)

The Paradise fish are very hardy, stunning, brightly coloured and add more activity to the aquarium with their interesting behaviours.

They are not suitable for the beginner aquarist though because they are challenging to handle, and they have an aggressive nature.

Slim, rectangular bodies and long flowing fins distinguish Paradise Fish. They also have two thread-like pelvic fins, like Gouramis. In general, this species has vibrant red and blue stripes on its body, two-tone fins, and an orange caudal fin. There may be a few blue-black spots scattered over their bodies occasionally.

In the home aquarium, the Paradise Fish will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.
