you could keep a PAIR of discus or one solitary showpiece discus in a 29 gallon. i would recommend not keeping more than two and only if they are a a pair at that. i would recommend starting off with discus in a bigger tank tho. its easier to keep up with water quality and the discus appreciate it much more and you can add more if you decide. a 75 or 90 would be ideal for a small group of 6-8 adults. be sure to have very good filtration and clean the junk off the substrate often.
some fine tankmates would be rams, most non-nippy tetras, ottos, smaller plecos, cories and some other small peaceful fish. as previously stated add the discus and algae eaters fisrt and let them acclimate to the tank before adding other fish.
i agree with driftwood, you should def keep up with water changes, the minumum should be one large or two or three smaller ones(15-25%) a week with a understocked discus tank.
discus are a really cool fish if you have the time and patience to take care of them.
p.s. when feeding the beefheart, you can add a lot of stuff to it, garlic powder, boiled eggs, live foods, color flakes, baby food, baby formula, and a host of other things that will help increase viatmins and color and especially growth. try adding more bloodworms to the first couple batches to try getting your discus to accept the rest of the mix.
