Please help, the second best lady in my life is losing her wonderful lower lip.
On Saturday morning I noticed she was hiding in the bottom of the tank where I was unable to find her for a good five minutes and when I did she looked unwell and would not eat her hikari pellets. So I checked her tank stats and everything turned out normal;
Ammonia = 0
Nitrite = 0
ph = 7.8
temp = 75 (now it is back up to 82)
Her only tank mate is a lone cherry shrimp (I think she ate my other cherry shrimp). I have had her 7-8 months she was a walmart rescue but has lived happily till now. Her 10 gal tank is fully cycled and has been for a while. It is filtered via a sponge system. The tank gets a water change weekly of about 20-25%.
I am at a loss as to what is eating away at her lip. Please help
