[13:48] <charliem> Gday Rm. Wattley
[13:49] <Jack_Wattley> Good day
[13:49] <Fishbaron> Hello
[13:50] <juan> Hello Rm. Wattley from Spain. (I know that you speak Spanish very well, that's ok?)
[13:50] <Jack_Wattley> that will be fine Juan - my wife is Puerto Rican

And as last chat expert we got Jack Wattley. Incredible what a nice man that is.
Behind Jack is Ron futrell standing.

[13:51] <Walter> What is the reason that you raise your fry separate from the parents. Because I found that a couple with fry is one of the things that makes the discus hobby so interesting.
[13:52] <Jack_Wattley> the only reason I raise the fry (20%) is because those are the pairs that will not raise their own young
[13:51] <Walter> Much has been made of your opinion on Growth Inhibiting Hormone and it's effect on discus growth rate. You once stated in your column in TFH that it is no problem for you in your hatchery since you do daily water changes of 40% daily. My question is this: do you still have the same belief about GIH, or have you different ideas now? It has been stated on a discus forum recently that you have recanted the statements you once believed about GIH. If you think differently now, what brought
[13:51] <Walter> about the change
[13:54] <Jack_Wattley> it's been proven that with any tropical fish in a confined area that the larger ones give off an alkaline toxin that inhibits the growth of the smaller fish. Naturally, in larger tanks with large water changes that toxin will be in smaller amounts and the effects will be lesser on the smaller fish.
[13:58] <Barrie> Hi from Australia Jack. I have some pairs that will keep their fry without problems. Other pairs will eat them at the free swimming stage. Is there any thing I should be improving on with the water to help this situation?
[14:03] <Jack_Wattley> Barrie, two things: one, you must determine which is eating the fry - find out which one and take them out - if that doesn't work, then next spawn take the female out - one parent can raise the fry alone.
[13:58] <Fishbaron> Much has been written about imprinting ( re parents that raise their own fry). What affect if any have you observed over the years regarding imprinting? How does this affect the ability of the discus as future parents?
[14:04] <Jack_Wattley> I never had a problem with that Fishbaron
[13:59] <juan> what kind of discus do you think that is the best discus ? and Why (color, forms, size, ...)?
[14:05] <Jack_Wattley> Juan, I think none are really stronger than others - the heckles are harder to breed than the others. My personal favorite is the Turq discus I developed :-)
[14:08] <Barrie> With artificial hatching, have you found anything to replace the brine shrimp seeing they are very difficult to get at the moment?
[14:10] <Jack_Wattley> Barrie, you can take a beefheart formula and put it in a blender and blend it down very fine and feed it to the fry - they grow even better on a good beefheart formula than they do on artemia
[14:10] <Jack_Wattley> you must be very careful because it will pollute the water - feed it very discreetly
[14:08] <juan> I have one pair: wild green female and red turq male. They have fry (30 days), my first fry. What can I do, in the future, to improve the discus? ("mejorar la raza")
[14:12] <Jack_Wattley> Juan, after second generation begin to back-cross.
[14:08] <charliem> Jack, how long would it take you to get a discus fish to 4-5 cm in size between 8 to 12 weeks
[14:13] <Jack_Wattley> Charliem, it takes about 12 weeks to get them to that size, not 8 weeks

[14:15] <juan> I have turq discus (high body). What is the definition of your best characteristics? (color eyes, lines, form)
[14:19] <Jack_Wattley> Juan, one, I don't like the body confirmation of the high-body discus. I don't think it's a natural looking discus. I think the best body form can be found in wild discus
[14:20] <Jack_Wattley> Most people feel discus with red eyes is an attribute - it doesn't mean fish is healthier (as opposed to gold-eyed), just more pleasing to the eye
[14:15] <Barrie> Jack, how do you prepare your RO water for your breeding pairs?
[14:16] <Barrie> Jack, do you have any experience in preparing tap water that has chloramines in it? I use this for the growing of the young.
[14:21] <Jack_Wattley> we mix r/o water more or less 75%, with 25% city water. The city water has chloramines in the water and we must remove the chloramines with activated chloramines.
[14:23] <juan> When you said back-cross, you said that I cross sister with brother or mother with brother or father with sister? (I don't know how translate back-cross, sorry ) :-(. Why "second generations"
[14:29] <juan> When de fry has one month, what is the best diet for them, and what your water conditions?
[14:34] <Jack_Wattley> Juan, mother with brother and/or father with sister. Second generation because the higher the generation, the more defects you will get in the fish. After about two more generations, you might want to consider out-crossing (bringing in new blood - wild is best)
[14:30] <Barrie> I am very sorry. I lost my connection before I could read your responses to my two questions. One on preparing RO water the other on chloramines. Would you mind repeating the answers.
[14:36] <Jack_Wattley> we mix r/o water more or less 75%, with 25% city water. The city water has chloramines in the water and so we remove it with activated charcoal.
[14:32] <Walter> (question from Jorge) Is it nessasary to use carbon in filters in discus tanks?
[14:39] <Jack_Wattley> Jorge, if you use carbon on continuous basis, then it indicates you have a water pollution problem. Large quantities of carbon will remove the protective slime coating that discus have (between 10 days-2wks) . This happens mainly with the larger fish. If there's carbon in the filter will make the water clearer but large quantities will subject them to bacteria invasions. We never use carbon
[14:35] <Barrie> Jack, is there anywhere in Australia that you know of that has your original "Wattley Turquoise"? Somewhere I can get some babies.
[14:41] <Jack_Wattley> Barrie, no I don't. I have a good friend in Australia but he doesn't have discus.
[14:45] <Walter> How do you keep your young fish in a healthy condition ? What I mean is, do you use any medications regularly to keep young discus healthy during their growing-up stage until they become adults ? 
[14:47] <Jack_Wattley> two word answer - absolutely not!!! We very seldom use medications. We lower ph if bacteria is the problem - bringing it down in 3 days to ph of 4.0 will kill all harmful bacteria
[14:48] <Jack_Wattley> IF A parasitic problem (internal) we add fresh garlic to our beefheart formula and that will take care of it
[14:45] <juan> I asked Mr. Wattley by the best food an water conditions for the babies (one month) :-)
[14:49] <juan> is it bad for the fry (one month ) pH 7,5 and 330 mS (conductivity)?
[14:56] <Jack_Wattley> water conditions were ph between 5.0 5.5, temp 90F, high conductivity (the fry grow better with a high mineral content in the water). large water changes are very beneficial to rapid growth if you have good water available, daily changes of 40 to 50% are excellent -
[14:49] <Barrie> How much garlic do you suggest Jack?
[15:00] <Jack_Wattley> garlic must be freshly squeezed add to the formula your feeding, quantity
[14:54] <Jack_Wattley> Barrie, you can take a beefheart formula and put it in a blender and blend it down very fine and feed it to the fry - they grow even better on a good beefheart formula than they do on artemia  they like it very much
[14:51] <Barrie> Once again I got thrown off before I could read your response to the availability of your turquoise in Australia.
[14:59] <Jack_Wattley> no Barrie, I don't
[14:59] <juan> High conductivity : ?400, 500 , 700 mS ?
being as much as 30-40% garlic
[15:01] <Barrie> Is that just juice or pulp from the garlic?
[15:05] <Jack_Wattley> Barrie, you won't get really juice - it'll be puree (not really pulp) and you must feed it to the fish every day for at least 30 days before you will see results. The garlic will not kill the parasites, they will leave the fish and the reproductive cycle of the parasites will be broken.
[15:03] <juan> The water on my region don't permit good quality (sea water purified) . I can lower the ph to 5,5 even with phosforico ac.
[15:05] <Jack_Wattley> yes, Juan, that's okay
[15:04] <juan> how can I stabilize the ph ?
[15:06] <Jack_Wattley> there are products on the market for stabilizing the ph - we do not have the need to do it.
[15:07] <Jack_Wattley> massive water changes will eliminate the stabilization problem
[15:08] <Jack_Wattley> Juan, high conductivity of 700mS is fine and if you have well water (very clean) that is great.
[15:09] <Jack_Wattley> this is only for the young fish - the hard water is excellent as long as they are still in their growing period
[15:10] <Jack_Wattley> Thank you all for your questions - I have enjoyed it very much
[15:10] <Walter> Jack thank you also for joining our chat today and we loved it all.
