So i had an endlicheri, for the last 4/5 months. Completely healthy(i thought) ate regularly. Last night fed it a freeze dried shrimp. Went to work this morning it was fine. Came home rn and its belly up at the bottom of the tank. I just tested my water and all the levels were normal besides my nitrates. Now idk if its bc the fish was dead sitting in there or somethings wrong. I have a feeling the freeze dried shrimp mighta killed it. Any ideas? Suggestions? I might cry i ahd it since it was 1 inch. Died at 10 inches.
 
I’d look at ur water. Nitrates being high can kill fish. Gotta increase ur water changes from what I’m looking at it.

I just switched from a hob filter to a fluvac x4 or whatever about 2 weeks ago. i change it ever week. Makes no sense the sudden spike
