Any pathogens. Fish tank water is disgusting no matter how many water changes you do.So I'm curious, what will make the wound get infected? Bad water?
Here's
When I worked as a microbiologist, I tested my tank water a number of times for total coliform, E coli, and various other heterotrophic bacteria. All coliform counts on a 100ml sample were off the charts, and hetertrophs too numerous to count using the pour plate methods. This does not mean all the bacteria were pathogenic, it just means in 100 mls of sample, bacterial populations were so high, they were like a bacterial soup, and if too much was swallowed might illicit the bodies flush response to rid itself of those that might become problematic if left to reproduce.
