Well 3 discus and maybe a few otos is about the max for a 29G. Well discus need high temps 84-88*F, pH around 6.2-6.6, moderatly and moderatly soft water. They like live plants and look great swimming threw them. The need a diet mainly of frozen foods. I use beefheart(homemade kind, not the kind from the LPS), frozen bloodworms, frozen krill, discus pellets, FreezeDried bloodworms & spirulina flakes. You will need excellent filtration, preferably a canister since it doesn't create so much water movement. If ya wanna keep discus you must like to do waterchanges, IMO twice weekly of 20% is oK more is better. Thats about it, discus arn't hard if you give them what they want. GoodLuck!
