hI guys! So I have 3 tanks and all my params are the same. ph is 7.6 0 amm 0 nitrites and nitrate has never been above 5ppm. For some reason snails always die in my big tank. Nerite snails and mystery snails so far. I had 1 doing great for nearly a year with my betta and it dies within 2 weeks of me moving it to the bigger tank and ive had 3 newbies from the store die in there too. Any idea what could be causing this? If this tank is just a snail murdering mystery then any suggestions on something to control algae in a 45g community tank? Id prefer not to add another school because I already have rummynose tetras, panda corys and cherry barbs in there. I also have a group of honey gouramis and a pair of bolivian rams. Thanks so much!!
