Hello guys I really need your help. 10gal with buffer, 4 corys
(2 spotted/peppered 2 Julie) 2 Amano shrimp
:~150 ph:7-7.5 NO2
: 0ppm NO3
Using water drop test for ammonia all others are through test strip which i did x2
I came home the other day to find one Julie corydora dead on the bottom of the tank, and another cory(Peppered) swimming in corkscrews landing upside down with heavy breathing. I ended up euthanizing that one because he could not move at all without corkscrewing. Now today I find my last Julie cory corkscrewing around the tank landing upside down but after a small rest went right back to swimming normally.(5 min ago) I have no idea what is wrong plz help! I'm performing a water change and tank clean right now to lower the ammonia.
Thanks to anyone who can offer up some advice
