Exclamation Peppered cories losing Barbels!!

Two of my peppered cories have lost a barbel on one side, I think it might be becuase of the substrate but everywhere i look the type i have seems to be fine, should i switch to sand???

definatly switch to sand, they will hurt themselves and thier bellies on gravel! you could put a layer over the gravel, but eventualy it will just mix together

Subject: Larry LaPrise dead at 93

With all the sadness and trauma going on in the world at the moment, it is worth reflecting on the death of a very important person, which almost went unnoticed last week.

Larry LaPrise, the man that wrote "The Hokey Pokey" died peacefully at the age of 93. The most traumatic part for his family was getting him into the coffin. They put his left leg in. And then the trouble started.

Sand is the often-recommended substrate for bottom fish like Corydoras that root in it continually, but small-grain gravel will work fine if it does not have sharp endges. I have mainted dozens of Corydoras fish over 15 years with gravel.

There is some thinking that nitrates cause barbel loss, and others think detrius on the substrate (the bacteria associate with it). Dr. David Sands, an acknowledged authority on Corydoras, has written that barbel loss is not connected to the type of substrate unless it is sharp. As long as the gravel is fine and smooth in your hand, it should be OK.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
