Hi I've recently bought 2 reed fish but I don't know much about them so any info would be appreciated I currently have them in a 2 1/2 foot tank with 10 barbs and 2 butterfly fish I know I got to upgrade the size of my tank but don't know how big to go could I get away with a 3 foot tank ? I was told that the reed fish can get up to 3 foot in the wild and only 1foot in a tank
