My friend Marcel is a gifted aquarist with a true talent for planted aquariums, aquascaping and breeding rainbow fish. He maintains two large planted tanks (180 gallon and 72 gallon) as displays, and a small nano aquarium that is his ‘experiment’… natural light, no filtration, no heat and only snails and shrimp for fauna. You will get a good look at all of them in the video. Marcel also applies the basic principles from his planted displays to his rainbow fish breeding and rearing tanks in the basement. One of the keys to his success with planted aquariums is layered substrates, which he also makes us of in his breeding tanks by planting on pots. Thank you Marcel for letting us in for a glimpse of your fish room!
