Walter Hello Mr Yeng nice to see you here.
Shaifullah-Yeng Hello All. Do we have a question?
fredg hello
fredg on your method of treating the eggs with Methlyne Blue... have you changed it since the first edition of your book?
Shaifullah-Yeng no, no reason for changing because it works we have not changed our system for breeding
fredg If I may a second one in a row
Shaifullah-Yeng yes, please
fredg With your work with RSG, would you say that they will lead to the "next" step in domestic "strains" or "types" of discus?
Shaifullah-Yeng I think we are working toward a stain - the wild RSG has small, non-perfect spots with short striations while we are working... to develop a strain with good striations and between the straitions, spots
Karsten Shaifullah, I talked to Horst today about the new german Version of your book, when is it to be expected ?
Shaifullah-Yeng Karsten - we have scheduled it to be released early November
Karsten ty
Dougall I was wondering if in your experience the average discus breeder should be concerned with the transmittance of disease through the use of live food in general - if yes - is there a favourite live food that you use for rearing young discus?
Shaifullah-Yeng very good question Dougall let me answer yes, they should be concerned...the use of live food can bring along with it flaglettis, flukes...it depends on the situation of the fish - if small fishes, be careful with use of artemia as it brings in odinium... to avoid this I normally use beefheart mix, shrimps with fish fillets, shrimps, very finely grated I think best food (although I do not use it) is live earthworms even frozen bloodworms have bacterias and parasites that have not been eradicated in the process of being frozen
Dougall thank you very much I too like frozen or freshly mixed feeds I completely agree
Shaifullah-Yeng what do you use for your prepared foods dougall?
Dougall I use beefheart and cod fillets with spirulina and lechithin with a touch of garlic - it was a food mix suggested by Fred
Shaifullah-Yeng I like the garlic, yes - it smells bad but is good for the fish hahaha
Dougall yes indeed :-) Brenda (my wife) wont let me anywhere near the kitchen when I have to make a mix up - she makes me go outside in the cold :-(
Shaifullah-Yeng } hahaha@Dougall/Brenda
Dougall on occasion I have used lamb hearts but these take a great deal of preperation :-(
Shaifullah-Yeng we don't use lamb hearts
Glenn What are your favorite strains of discus? In your opinion, what are the best selling strains of discus?
Shaifullah-Yeng my favorite strain is the brown discus...forget the word "strain" haha best selling I think is spotted discus - spots enhance the texture of the fish rather than just having the striations...I don't like the white discus it's very weak and for no reason just dies - I only can guess they are very weak genetically because they are....mutation from the ghost (which is also a mutation)
Dougall What is the largest discus you have personally seen? (from lip to caudal fin)? and was it one for yours or a friends? and if you could only give 3 pieces of advice into the secret of growing super large discus with good shape what would that be? thank you.
Shaifullah-Yeng largest discus tip to tip about 17 cm...mine and I've seen it also from other breeders although it is not common 1)contanst temp, constant ph and 3) a variety of foods regular feedings TLC fishes that are too large do not spawn well large or thick
Dougall thank you very much - I did not know that about large fish not spawning well
Shaifullah-Yeng yes, our favorite sizes for spawning is about 14cm to 15-16 cm most Asian fish are about this size
Dougall You are very kind for sharing your time but I must let others chat with you too - yes it is a size I would expect to see at the GOOD breeders
Shaifullah-Yeng what is the largest fish you have had and how did you get him to that size?
Dougall the largest would be about 15cm and regular feedings, regular water changes and lots of patience
Shaifullah-Yeng ok, see you soon dougall
Dougall people said after a year he would not get bigger (he was 10cm then) - but I didnt tell him that as I didnt want to hurt his feelings - and then a year later he reached 15cm
Shaifullah-Yeng hahaha
Andrew Is there a particular age you believe the male and female could give you the "strongest " spawn? Good genetics..
Shaifullah-Yeng no
Karsten Mr. Yeng, "Constant Temp, PH & TLC for growing out Large Fish" would you recommend any specific PH & Temp?
Shaifullah-Yeng yes pH best is 6.8 temp about 28Cif you have higher in planted tank, the plants do not do well is your tank bare bottom or planted/decorated?
Glenn Are you going to write another discus book? IMO, Penang Discus is probably the best written so far.
Shaifullah-Yeng thank you Glenn - I think not hahaha I actually have one in the works coming out in November
Karsten Do you recommend a specific conductivity in ppm for hatching eggs?
Shaifullah-Yeng conductivity 60-80ms is best and conductivity assuming you do no water changes (which is not recommended) if you are doing water changes, this will shift the water quality and may affect the hatching of the eggs or even eggs just die off...will change the osmotic pressure and cause them to die so keep between 60-80ms, siphon bottom but add no water (unless water is exactly same) for raising discus, it is better to have slightly hard water, say 400ms this is for 1.5 inches up
Karsten Mr. Yeng, 60-80ms for hatching eggs along without changing the water chemistry the first 2 days during hatching is an excellent tip for all of us. Also maintaining a hardness of 250- 300us, constant PH & Temp during grow out is a tip I will always remember
Shaifullah-Yeng fry should be raised to 1.5 inches in breeding water sizes specify nose to end of tail (total length - TL)
Walter Mr. Yeng I have a breeding pair which I have recently got from a friend, the pair have not spawned in 3 years, they are happy and displaying to each other but will not spawn. Do you have any tips to help me to induce them to spawn ?
Shaifullah-Yeng are you sure it is a pair?
Walter yes
Shaifullah-Yeng ok, what strain is it?
Walter brilliant turquoise
Shaifullah-Yeng these should begin to spawn within 18 months unless that pair is stunted, hormone treated early on when small, ms 60-80...\par what foods are you using? should give them some live foods like fresh oysters mixed into prepared foods
Walter well the pair were bought as a breeding pair but the friend I got them from did not keep them in optimum water therefore they did not spawn. I make my own beefheart mix I also feed them white worms and tetra bits
Shaifullah-Yeng maybe 5gms (oysters) to 100gms (prepared food) - be careful it will pollute water so bind together well
Karsten Mr Yeng, would you recommend a binder in your oyster & food preperation
Shaifullah-Yeng [Karsten] we use CMC (carboxylmethylcellulose) to bind the food...just mix a little in the food and it sticks
Andrew I have heard the use of marine salt to change the conductivety, would that help Walter to trigger his pair?
Dougall my appologies for interupting, if walter were to use the salt, to what should he raise his ms to?
Shaifullah-Yeng using rock salt, table salt, or what?
Andrew Marine salt as used in salt water tanks... interesting you mention the use of oyters... they are raised in salt water...
Walter no Salt
Shaifullah-Yeng [Dougall] need to know what kind of salt before I can answer
Dougall sorry rock salt would be my favourite
Shaifullah-Yeng sodium chloride is not good I would say do not use it when eggs are present
Dougall ok I understand - how would you use the salt to trigger spawning or did I misunderstand?
Andrew With the use of Marine salt (ocean) to make a minor fluctuation in the conductivity of the water to trigger the spawn...
Shaifullah-Yeng no, didn't say that, triggering spawning for turqs is the oyster in prepared food
Dougall thanks - my error
John_Hernandez Is feeding bloodworm "Frozen" a good source of nutitrition for my fish?
Shaifullah-Yeng no john because too many problems HIH, flagellites, flukes - many parasites are brought in with these foods
Andrew thank you
Shaifullah-Yeng ok, must go now - it is after 2:00 - thank you for your questions
Andrew thank you
John_Hernandez Thank you Yeng
fredg Mr. Yeng, thank you for your time
Walter Thank You
Dougall thank you & enjoy the show and the good people there
Glenn Time to change water. Cya!
