I used to breed discus back in the day, and i used to sell all the fry for 5 bucks.. I had a guy that was in wholesale that would take the whole spawn.. I would keep a few of the best or if something was out of the ordinary, then sell them the rest.. now if someone I knew came off the street the price was 10 bucks, because there only going to buy a few so the price has to go up, here's why the price is so high.. it's mostly food cost, the longer you have the fish, the more food they eat.. also some of those exotic strains with the dots they are alot more money because you have to buy them at a larger size for one, and also there only might be a few in the entire batch so the price as to go way up for that.. but your basic strains like blue diamonds and stuff those are cheap.. don't pay big bucks for them..
first you can't sex small discus, you can come close but no proven method.. so to get a male and female you usually have to buy 6. then feed them for the next year, and some strains will take almost 2 years until they will pair up, now food and water and you have to have good equipment.. heaters, I always had to buy 250 -300 watt so your electric bill will go up, and you need at least 75 or 90 gallon tanks so you don't stun their growth.. you will need a breeding tank about 29 gallons is the best.. and then you will need a grow out tank after that so you can get the fry to size to get rid of then quick.. I used a 55 gallon for that... food is the most expensive thing.. small discus need to be fed 6 -7 times a day, to get them up to a good size, and also keep them in tip top condition ready for spawning... now lets say you did all this and they are all grown up and you finally see some eggs laid. now you put them in a the 29g tank, and now you need to have the water soft, so you must come up with an r/o system or another way to soften water, and there are many ways.. finding the cheapest way is best.. you get fry and watch them grow... now this sounds simple and it does take some time. but to get to my first successful, and raise fry for selling it took my almost 3 years, I lost everything 3 times, I got hit with the black plague. and then I stopped doing fish for a bit, and then got determined. 1 year later fry... if you want some words of advice, here you go..
1) go on some discus forums you might find some cheap
2) go to a discus breeders house and they will usually cut you a deal if you buy a bunch of fish from them,, I did this and I got 6 of each and walked away with 7 different strains... but the catch was the smallest one was a dime size, and the largest was a quarter, but i knew that I could take care of them, and he was comfortable to sell them to me that size...
3) just buy a breeding pair (proven) you might pay a little more but it will be worth it in the end... this way you don't waste a year of your time trying to get them to pair up, and you can spend that time watching the parents raise the fry... which is probably the best site ever to see...
another thing that I forgot.. alot of people are importing the discus now. they think there going to make big bucks off of them, but in reality they don't, they have to order 7 boxes of fish, and from what I was told, it's like 1400 just in shipping cost, so they buy the fish cheap and them add the shipping cost to each fish, there's another reason the fish are such a high price.. another thing some of the fish from over seas are hormoned, so they won't look like they do in the pics for long
if anyone has anymore questions or anything feel free to ask..
