One of my peppered corys seems to be having trouble staying grounded. He is getting around ok and eating but soon as he pauses for a split second, he starts to float upward :( I have had him for 1 year, water parameters:
Ammonia 0
Nitrite 0
Nitrate 5
Ph 6.8
temp 29
I have 8 other corys that are perfectly fine!
Any help much appreciated :wink:
