Diary of Breeding Discus (photos)
Author: F6F (aquariumfarm, HK)
Translation: JoJo (aquariumfarm, HK)
Original thread in Chinese: http://aquariumfarm.com/phpBB2/viewtopic.php?t=54735

My discus had eggs several years ago, I recorded the breeding process. I hope it helps most of the fishkeepers who wants to breed discus.

Breed: a pair of Cobalt Blue Turquoise, which had the experiences of breeding several times.
Size of the aquarium: 15” x 19” x 16”
Water temperature: 30℃
Filter: AA (brand name) overtank external filter & sponge filter
Filter media: general white filter pads

Left: female / Right: male

Before breeding –
They were both placed in the same aquarium. They were cleaning the ceramic egg layer. It means that they were already to breed eggs. It is OK to feed before breeding. Do not to feed any food, which causes high water pollution.
圖檔

breeding eggs –
Day 1: some of the fertilized eggs were brown in colour. The eggs which were not fertilized became white.

Important points of the percentages of successfully spawning eggs –
1. The percentage will be reduced if both of them do not have many breeding experiences.
2. Water temperature: I usually keep 30℃ – 32℃.
3. Water condition: Do not perform water-change at the moment. Stop using the filter to avoid the new-born discus fry getting sucked into the inlet. It is better to use sponge filter, which is safe for the babies.
4. Feels safety: It is important not to disturb, if they have had no breeding experience. They will probably eat the eggs when frightened. Do not touch anything in the tank, including water changes. It is OK to switch on the aquarium light, surrounding the aquarium with a piece of black cloth is recommended.
圖檔

From the photos, you can see the difference between the colours of the fish before and after breeding. Their colours are darker after breeding because they secrete something like “milk” to feed their babies, until the new-born discus no longer needs it. The food of new-born discus and the other spicies of fishes are different. New-born discus needs to be fed with “milk” in the first 1-2 weeks. If the parents have not had breeding experience or there is not enough “milk” to feed their young, the young will probably die.
(Left: before breeding / Right: after breeding)

Day 2: It is still necessary to a feed small amount of frozen blood-worm to the parents, do not overfeed to avoid bad water condition. Do not perform water changes at this stage, so it is suggested to use a bigger size of aquarium.

Day 3: The parents take care of their young. Do not perform water change. Also, a small amount of feeding is necessary.
(Because I lost the photo, I use this photo to describe. You can see the tails of the eggs)
圖檔

Day 4: The new-born discus breeding from the eggs. They are in a group and it is easier for the parents to take care of them. Do not perform water changes and, again, a small amount of feeding is necessary.

Day 5: The new-born discus start to eat the “milk” food, which is secreted from their parents.
圖檔
(The Discus’ nitrogenous waste piles up because due to the lack of water changes for several days. It is still reasonably harmless. Therefore, it is not necessary to clear it at the moment)
圖檔

Day 6: A small amount of feeding is necessary. It is okay to perform 1/4 water change as all the newborn discus know to feed themselves with their parents’ “milk”. It is now important to add fresh water with a temperature that is the same as the tank water temperature. The fresh water needs to be added slowly to avoid affecting the new-born discus, which will still be fragile.
圖檔

A pair of good parents feed their young. It increases the percentages of keeping all the new-born discus alive and in good health. If one of them does not feed their young, it probably will cause some of the new-born discus to die.
圖檔

圖檔

Day 7: The new-born discus are getting bigger. It is okay to perform a 1/5 to 1/4 water change. Small amount of feeding (frozen blood-worm) is necessary.
圖檔

Day 8: The new-born discus are growing up and they have started to swim a distance away from their parents.
圖檔

Day 11:
圖檔

Day 12: The colours of the parents are still dark.
圖檔

Day 13:
圖檔
圖檔

Day 14:
It is OK to feed BBS (Brine Shrimp). Feeding a small amount of BBS several times in a day is recommended. Increasing water changes is necessary. Perform 1/3 water-change 2-3 time everyday. Some of the fish-keepers separate the parents. I think that it is okay to let the parents stay with their offspring for longer.
圖檔

Day 15: The small discus have started to swim away from their parents. At the stage it is okay to separate the parents and the young.
圖檔

The small discus are separated into another tank. The tank of the parents need water changes and feeding (other better food).

Size of aquarium: 24” x 19” 16”
Filter: Sponge filter only. The over-tank filter had been stopped and is no longer used.
Feeding BBS 4 times a day (every 4 hours).
圖檔

Day 17: The small discus start to eat BBS.
圖檔

Day 20:
圖檔

Day 28:
圖檔

Day 34: The over-tank filter will be used. It needs to be surrounded by a piece of net to avoid the small discus getting sucked into the inlet.
圖檔

Day 53: I stopped feeding BBS to the small discus. I have started to feed “beef heart & shrimps”, which help to improve the health and colours. Actually, it is OK to feed frozen bloodworms and “beef heart shrimps” mixed with BBS from day 40. Some of the small discus still need to be fed with BBS.

A year later, they are growing up.

老外水族網站時常有人會問 "如何分辦公母七彩神仙", 我試過搜尋, 但沒有結果... 我想翻譯這個主題啊, 如有的話請幫忙 :-D

最近看到有個英國人發帖, 養了一對七彩神仙, 之前生了很多小魚 (約 40 條), 他說自己沒有錢, 不想再開新魚缸, 不想牠們繼續交配, 問網友們有什麼辦法. 我覺得好好笑, 賣左小魚咪可以賺錢囉 :mrgreen:

其實好睇七彩小魚的魚種的 :-) 當然每個地方飼養者的喜愛各有不同,加上外國玩水族的費用好像很高,就個人看法普通的七彩無太多人有興趣,送就另計 :-) 七彩分別公現在還沒有適合的文章,如有會通知你的 :-) 謝謝JoJo無私奉獻 [em23]

其實很多老外愛養七彩神仙, 目的是多生小魚, 養大後去賣 :mrgreen: 如果我養到靚既我都會, 不過, 硬水很難養到好靚...

我最近在家悶到發癲 (因為待產), 所以先至搞搞翻譯田園文章 :mrgreen: 我在田園學養魚種草, 有點小奉獻是應該的.

其實賣魚是很難的,由其是好像我地依些外行人,散左出來好像很開心,但到養了兩三個月大,BB 魚開始有番咁上下 size,會是一個很頭痛的問題,賣出去又無門路,拿出去金魚街,簡直會當係垃圾,好既可能比番幾百蚊你,真係紅蟲錢都唔夠食 2 個星期,如你有門路,可介紹下我

只是神仙魚在英國比較值錢, 不是香港. 香港咩魚都有, 當然唔值錢啦.
