I have a 10 gallon QT tank that I'm putting my discus into before putting them in the 110 gallon. The LFS has pigeon blood that are 3-4" for $60.00 or 3 for $150.00 so I want to get 3.
How many will fit in the 10 gallon? None a 10 is too small even for temporary housing.
Should I only get 1 at a time?I would recommend getting more optimally you need 4-5 to diffuse aggression. Discus are not the calm passive fish you might believe. they are still, after all, Cichlids.
Will only 1 discus get lonely being by itself for a month? see above
If I get one at a time, it'll take 3 months just to get 3 fish in the 110 gallon, but I don't want to do anything wrong. What are the thoughts? get a larger tank and stock 4-5 discus. you can do this with a 29-30 if you buy juveniles, they will need frequent water changes and several feedings per day(4-5) this usually means lots of cleaning up.
discus are foragers and will forage all day long.
