Hello again! So I posted a few days ago about losing four bettas in two days. So far, so good, no more losses.......of bettas. HOWEVER. My hubby bought me five neon tetras and a new betta for a different tank for my bday. The tank had just finished cycling and all was fine for three days until the neons came down with ich. Treated the tank, lost some neons and my cycle. (Ich absolutely came from the pet store. We went in for angels and looked at the neons to see if they had it at the store and they were covered. The 'fish specialist ' had no idea. Also couldn't tell the difference between male and female bettas. Grrr...) We bought three small angels and one rainbow shark for a different aquarium that day after being assured that the tanks were all on different filtration systems. Two days later, angel one died. Next day, angel two died and shark was fine. No marks or spots of any kind on the angels. Zero tranfer of ANY equipment from my tanks. Took everybody back today because maybe angels are just too...finicky?? 20 gal, 0 amm and nitrites, 10 nitrates, 80*f, ph 7.6. I use apI master kit. They used strips at the store today and told me my water is perfect. Head smack. Duh. Came home with another betta and 5 emerald cories. One hour after acclimating, I have an upside down cory breathing heavily. Even did a 50% wc before I brought the new fish home. What the WHAT is going on?!?! Have I been unlucky enough to get bad fish?? There are no breeders around me. Is it me? I can keep bettas and cichlids and oscars alive for years, but everything lately is dying?!?! Sorry for the novel, I'm just at my wits end and about to be done! Can you really have a run of bad luck with fish purchases????
