I've had freshwater tanks for a long time, but saltwater aquariums have always fascinated me. At one point I decided that I'd set up a small 50 L cube and I've already been in this hobby for 5 years, spending most of my free time developing my knowledge and skills. Now I managed to combine my hobby with work and I'm super happy.
What I value the most in marine aquaristics is the diversity of species and behavior of animals, even the smallest ones, which can be observed, for example, at night, after a hard day at work. Nothing is as relaxing as staring at a tank teeming with life.
