I would not buy fish from anyone like that. But why the huge price jumps when it comes to Discus? Well more than anything is they eat a lot for a small fish and they won't eat the cheep stuff. I get my discus for $9.00 to $18.00 at 2". When the Discus get to about 5" the same people will buy them back at $25.00 to $65.00. That looks like a good way for me to make some money? NO. So Buy a Discus at $9.00 at 2" that Discus will cost about $2.50 a week to feed and about 5 weeks to grow a inch thats about $15.00 an inch in food. So 9.00 for the 2" fish $45.00 in food to sell it at $25.00 so I'm out $29.00. Note a breeder is not going to spend $2.50 per fish to feed a week, more like $.10 a fish. But someone with just one to five fish most of the time will be. Most people see Discus and fall in love. Then they'll go out get a tank set it up, spend about $140.00 a fish becuse they want good ones. Out of the first batch or two they will loose most of the fish, then in about 4 months they get it down and have a tank of Discus. They show their friends and coworkers and they are happy for about a month or two. Then the tank becomes a lot of work and money to keep up for some fish that never looked as cool as the one they seen in that one place that one time. But they just can't get rid of the tank and fish they unlike other first time fishkeepers, they have allready put way too much money into it just to flush it all away. Most people like this have put out over $5,000 on a frist time tank that they had set up for less than 6 months. Unlike most life time fishkeepers most of wich spent less than $20.00 on their frist set up, fish and all. Well they want their $5,000 back, not going to happen but they are going to try very hard to. And thats why you will see people trying to sell $40.00 fish for over $200.00. Most for this fish are in poor shape at best.
