Dionaea Dentate, Dente, and Dentate Traps, are ALL the same. When a plant from a Red Piranha (example) has germinated, even if it looks Identical to the mother. It is NOT a Red Piranha. Just because a leaf is turning black means nothing, it is part of the natural growth cycle for the Dionaea. If you see a flower stalk, cut it off immeadeiatly, even if you think they have to do it, or they have to do it in the wild, you're wrong. Some plants just don't flower. Only use Maxsea fertilizer. No other one. I'm sure there are more, but I am also sure that that one is safe. For Neps, you can use coffee and betta pellets as fertilizer. The coffee SIGNIFICANTLY makes the pitchers have a huge growth sport. Maybe it stays all night up growing . Dentate does not go against flytraps, as it was found that way, and it's genetics wanted it that way.
