Has any importer noticed most of the red and Red spotted color fish were hard to treat and some might died without external symtoms during the quarantine period ?
To quarantine the fish without the proper source is just like playing a gamble.
Out of ten shipments for just one is enough for you to scratch your head , plus the profits you made from the 9 shipments will go into the drain,if you keep the un-quarantined new arrivals in the same building,no matter how clever you are and how tight your isolation would be ,adult fish normally no problem if they have built up the anti-bodies,but,discus fries will say bye! bye! to you,you will find they have sticky tails and hard to raise after separate from parents,sooner or later you will swear like rabbits.
I got bad experience twice and have no gut in attempting the 3rd time for un-quarantined Discus in my premise.also,I pity the hobbyists for wasting their money on bad quality fish.
Not just formalin alone in the blood stream,there are others toxic chemical that damage the gut,liver and spleen. during quarantine period some shipments you might not find any symtom till the onset of the damages of internal organs at the hobbyists' tanks.I used to sent for analysis at our local fishery and they found and told me.also,friend of mine in Australia has the same problem after one import from a well known farm in Malaysia,report was almost the same.
I got burnt by Discus on consignment,so,I am now only looking for breeders who can follow my instruction,but,I won't tell them too much,because they have no royalty,whoever buy from them they will sell and tell.as the trade secret I also thanks for people in the same trade of our region not to visit our farm. hahaha!!!!!!!!!!!!!!that's the way,Mate!
So,if you are going to import the Discus make sure they carry the first quarantine long enough before shipment,so,you don't have to pay freight for culls and un-wanted shapes to carry out the second quarantine in your premise,this way you don't have to close your door when customers visiting you and you sayh! I have just sold them out to somewhere,I will keep you informed when I have the stocks.I think this statement is very common to many hobbyists for they don't want to show they have sick fish all over the farms,this is normal for the prevention of hobbyists might tell the competitor when they visiting next.
***Quarantine and Quality control is similar to Shoalin Temple.***
Have you guys seen the movies" Shoalin Temple?
when the munks wish to go out of the temple they must conquer the 18 Brass men,so,I wish dealers can follow this policy"Quarantine and Quality Control" before sales as to help the hobbyists to have healthy Discus and Hobbyists don't mind pay a little bit more to the dealers for the hard work done on your Discus.I am sure the problem of NEW and Old Discus problem in your community tank will have less problem.
I am sorry for this post ,no offence ,please.
