-How to Determine the Sex of a Discus Fish

Determining the sex of a discus fish is not an easy task. There are a lot of different opinions online about how to determine the sex of a discus fish.

When discus fish are small under 4 inches in size their dorsal (back) fin are always rounded. Therefore it is impossible to tell if a young discus under 4 inches in size is male or female! If anyone that is selling discus claims to know male versus female and the fish is under 4 inches in size- they are probably lying to make a quick sale!

When a discus reaches 4 inches of size or larger the shape of the dorsal fin changes.

If dorsal fin is rounded on the corners = FEMALE
If dorsal fine is pointed on the corners – MALE

Also- a male discus is always larger than the female.

The shape of the dorsal fin is a good indicator of sex but not always 100% accurate.

The only true 100% accurate way to know determine sex of a discus fish is to actually witness them spawning.
The fish that lays eggs is obviously the female.
The fish that swims over the eggs after they have been laid is the male.

If you have a discus lay eggs but the eggs never hatch there is a good chance that you have 2 female discus.

At Discusguy.com we never guarantee the sex of a discus regardless of their size unless we actually witness them spawning.

If you are looking to purchase a discus breeding pair be extremely careful and ask yourself and the sellers these questions:
1- If the pair is successfully spawning and producing fry why would they be selling them?
2- How old is the pair? The older the pair the less likely they will spawn.
3- How often to they spawn? If a pair spawns on a regular basis to produce fry to sell, the female may get burnt out and her health may be at risk. Reputable breeders make sure to give breeding pairs a break in between spawns in an effort not to jeopardize the health of the fish.
4- Where did the discus come from? Were they imported? Local breeder?
5- How many successful spawns have the pair had?
6- Why do they want to sell them in the first place?
7- Are they a PROVEN pair? If so, ask to see pictures of them spawning and pictures of the fry.

A less expensive alternative to getting a discus pair is to purchase 12 or more of the same discus strain/color when they are young. The odds of getting a breeding pair are usually pretty good. Many Discusguy.com customers have obtained breeding pairs in this manner.

I hope this information is helpful.

-All About Feeding Discus Fish

A very common question I get from customers is What are you feeding the discus? How often should I feed them? How much should I feed them?

There is a lot of conflicting information on the internet about feeding discus. I want to make this very simple for my customers.

Here is what I have been doing with my discus for many years with great success. All about feeding discus fish.

How Often Should I Feed My Discus?

    Under 3 months of age – feed ten to twelve times per day.

    3 to 12 months of age
    – feed up to five times per day.

    Over 12 months of age – feed two to three times per day.

    Be careful to not overfeed them. Overfeeding your discus could cause health problems and water pollution. Discus are sensitive fish who appreciate pristine water conditions.

    How much should I feed them?

Feed them only the amount of food that they can actively eat in about five minutes. Because discus have grinders in their jaws instead of teeth, they eat with this process: They mouth the food, spit it out, and then recapture it before swallowing. This process causes food particles to fall to the bottom of the tank, but the discus isn’t done yet! The discus can dispel water at foods resting on the bottom of the tank and then pick it up as it float upwards. After their main feeding, they will search for leftovers at the bottom of the tank and clean up the leftovers for up to an hour.

What should I feed them?

    Some discus enjoy food that is floating around, while others prefer the food that is at the bottom. Some discus will even eat food out of your hand!

    All of the fish at Discusguy.com are fed the following:

– High Protein Flake Food – Prime Reef Flakes by Ocean Nutrition. They can be purchased at any Petco store or online.
– Frozen Blood Worms – ONLY frozen! Not Live! Live worms can cause parasite issues! Stay away from live worms.
– Beef Heart Flakes – Purchased in bulk online- usually on Ebay.

What other foods can I feed Discus?

    – Tetra Bits – available online and in pet stores.
    – Home Made Beef Heart mix – many recipes available online.
    – Live Brine Shrimp – doesn’t have much nutritional value but is okay as an occasional treat.
