I posted a long-winded message on my old thread and realised probably no-one would read it Short version here! 25 US gallon tank, planted, 32 inches L x 12 inches W x 16 inches H. Sharp gravel so not suitable for bottom dwellers. 4 male guppies in currently, all getting along great. Final stocking plan: 5 male guppies 10 harlequin rasboras How does this sound? Aqadvisor thinks this is only 67% stocked but looking at the tank now, with just the 4 guppies, I think it will look pretty full with grown fish... Am I wrong? Also, how many fish should I add at a time and how often?
