Ok I have also found this is a great way to get another magic fish. If you Buy a set of the common Eggs in the shop you can get a Spined Fruit Fish. When that happens Breed:

Spined FruitFish & Greenfin Spotanus and get = Magic Speckles Leafish.
Sell this for $75-80 and wow you beed those fish and get a full tank to sell then buy your secound tank and you can breed more of the Magic Lea until you find another fish worth good money. I will update again when I have more. Please post and let me know if this has been helpful.
