Thanks for three all the advice. I really think it had something to do with the platys. I thought they were fine since I've had them for so long. Thanks everyone!
Davidiator I lost my elephant nose
Glad to hear the rest look fine.The rest of my fish look fine. I've read that the elephant nose are very sensitive. I did a little over 50% change and vacuumed the rocks very good. My poor baby whale is back in hiding without his friend.
I never mentioned platys ?You say you've had the platy's a long time, how long?
Platy's maximum life span is only 3 years, if they were already adult size when you bought them, they may have aged out.
