In the Danish aquarium forums, few people even know what cycling a tank is.. And those who do, always say that it isnt nessecery.. Its.. terrible. I'm Lucky to have a good lfs, in my area. Yeh, they make mistakes, but im yet to see Red Tail catfish, or Tiger shovelnoses there. They however always cut the sizes a Little of there larger predators. Like they list The Reticulatus stingrays and not growing larger than 35cm, and that kinda stuff. Maybe their just as bad, i never really ask them about anything. Theyr right now selling Tile Morays, but they Arent labeling them as freshwater morays, wich made me happy. Theres acually now info about them other than there name, but i have a feeling that if i ask, if they can go in full freshwater for life, im gonna get a yes.
