Discus are not any more difficult to keep than other tropical fish. Proper tank maintenance is required, discus can be shy and somewhat picky eaters if you are feeding them different food than what they are use to. A clean tank is a must when keeping discus, weekly partial water changes are recommended. A high water temperature is required, around 86 degrees Fahrenheit. Keep in mind, the cost of a discus fish is much more than other tropical fish. Keeping discus fish are not recommended for those who have never had an aquarium setup.

NO! Discus are very fragile fish- very sensitive Goldfish are messy plus, goldfish like temps in the 60's and discus like them in the 80's i can think of millions of other reasons do discus a favor and never keep them

No, green terrors are of the acara group who are generally less aggressive than Flowerhorns, which are extremley aggressive piscivorous predators (as opposed to acaras who browse for aquatic inverts etc.). And simply no mixing either of those with discus fish, In my opinion. Flowerhorns especially will easily kill a discus, all of whom are non aggressive
yes, of course a discus sleeps. Every fish sleeps.
It depends on what type of tropical fish you are intending to keep; it ranges from 6 (freshwater & discus) to 8.5 (for cichlids).
they arent -_-
what any discus eats.
no, discus are very slow moving fish zebras are one of the most active fishes. The zebras would stress the discus so much, they might die. If you want pretty fish that are also small, get cardinal or rummynose tetras.
