Lost my 2 BNPs to bloat in the last 2 weeks. I really miss them, so in the next couple of months, I want to set-up a species tank for some new BNPs.
If I do a 20 long, can I do 4 BNPs? Will they get along? AqAdvisor says I will be 85% stocked with 2 AC30s or 1 AC50, with obviously better filtration with the 2 filters.
Do I need two filters on a 20 long or is one HOB sufficient for the BNP's bioload?
