2 female swordfish, 4 x white clouds, 2xcory and 5xzebra danios which are very friendly and active is a recipe for disaster in a 35 litre tank - especially a tall narrow one like a biube.hi,
i've also got a similar size tank and i've got 2 female swordfish, 4 x white clouds, 2xcory and 5xzebra danios which are very friendly and active. i've certainly recommend the bronze or peppered cories. i also have a much larger 45 gal tank and found the cherry barbs, rasboras harlequins and dwarf neon rainbows are nice. i had 2 x male dwarf gouramis in my small tank but found them to be very terrorial, hence the larger tank.
Good luck with your new tank.
