My Tropical Fish Tanks. Keeping tropical fish, mainly Discus Fish and breeding them is one of my many hobbies... Enjoy the video! :) Sorry that there is no sound, but you can always play your own music while watching this video :) In my main custom made Aquarium (Fish Tank) & Cabinet / Hood (6ft x 2ft x 2ft): 7 x Adult Discus Fish (Symphysodon spp.) 1 x Black Ghost Knifefish (Apteronotus albifrons) 3 x Clown Loaches (Chromobotia macracanthus) 2 x Bristlenose Pleco (Ancistrus) - hiding :) and hundreds of Malaysian Trumpet Snails :) Mostly hiding in the gravel. They are absolutely no danger to the environment of the Aquarium. On the contrary, they make the Aquarium environment healthy. However, too much of them, just looks bad. Especially when you have them crawling on the glass :) But there are ways of controlling the population. If you have any questions, please do not hesitate to post a comment. Thank you for watching! :)
