Owning a 125l tropical aquarium, which I have had for 10yrs, sadly it's occupants were badly depleted, leaving only my catfish..(who is more submarine than fish) & a couple of tetras..my partner bought me a number of fish for my Birthday... which looked somewhat lost due to size..so I bought this mixed food selection to ensure they where able to get some .. which has worked perfectly as they are growing well & I no longer have to search for them... the food is excellent quality, lasts for awhile & has the added bonus of not clogging the filter or clouding the water.. highly recommended
