Hi, I was wondering what a safe number of smaller tetras for a 125 gallon tank would be I only have 7 right now 3 bleeding hearts and 4 red eyes. I will post pics if that would help.
The usual rule of thumb is one inch of fish per gallon.
This is actually not a valid rule..... just an old wive's tale. Best to take compatibility, bioload, environmental requirements, and the like into consideration when stocking a tank.
If I had a large tank like that, I would boost my schools to at least a dozen each of the schooling species. That would really make those schools POP!

This is an easy way new hobbyists to determine bioload so you dont overstock. Very crude, yes, but helps when your learning about the science behind the hobby.
And i dont think he'll have any problems with compatibility seeing as hows its just tetras he is getting.
It still doesn't fly with me. You can take fish of the same size and they will have a different bioload depending on the species, so I'm mystified as to why it would teach a newbie how to consider bioload.
Where would somebody learn the proper stocking of a tank then?
