Can anyone shed some light on the min tank requirement for a pearl gourami? I’ve seen a range of sizes from 15 gallon all the way to 55 gallon. I’m looking for the tank sizes of a single pearl, a duo, and a trio. Any help would be great!
They get almost 6", so I think they should be kept in a tank at least 36" long. I think something like a 30 gal (not a 30" long 29 gal) or a 40 breeder is a good minimum.
