Well today, I went to a lfs and saw that they have discus for only $17 each. Is that a good deal? They are around 3-4 inches in diameter. If it is, im thinking of getting one
If you're going to keep Discus... you're going to need more than 1.. Like.. 5.. is more like it. If you aren't looking to keep them in a group then Discus aren't for you..
hard to tell without a pic, but a discus that size, for that amount, from a lfs, I would say it's more than likely a waste of money. as water said one discus is a very bad idea. they are a social fish and need to be kept in groups of at least 5 or 6.
