Can i keep like a few baby discus(around1-4 inches) in a 5 gallon tank? Cause my flowerhorns/parrots/clown knifes/red devil already took the big tanks. Or how many small discus can i keep in a 5 gallon tank? Atleast 1?

No they need lots of room and care, only get discus if your going to be serious with them and put them first if you neglect them you will pay a price. You also need ot keep them with I believe a minimum of 3-4 discus, you can do 2 but it effects them in a bad way. If you got a spare 5 you will want to keep looking for something to out in there.

yup, discus need lots of space. too little space results in faster dirty water, therefore easier for the discus to be sick. discus are bit more sensitive than flowerhorn, they're not as hardy as flowerhorns. discus may seem to dont move much, but they also need the growing space. 5 gallon is way too small. For discus, i would say at least a 30 gallon, i would do 55 gallon, but if you really have to 30 gallon will work for a while. well goodluck

I suggest 1 discus per 10 gallon

let me rephrase it. IS IT POSSIBLE to keep like a few in a 5 gallon tank? How about a 10 gallon tank?

yes its possible but not for long term maybe a temp space to hold while u get a bigger tank

it is possible if for a VERY SMALL time, but they will be depressed, unless they are less then 2"
