I've kept many puffers and know many people who keeps puffers. A scientist on another forum that I visit would describe "FW
compromising the immune system of the figure 8", so it ends up getting sick often during its lifespan in FW
. You can only treat a sick fish so many times before it ends up dying.
I only know puffers really well, but kinda know some info on other fishes. Basicially, the FW
section of this forum is seperated into
2. all other freshwater fish
Thats what makes me think
Just do a lot of research about the fishes you already own. You'll figure out what is best for your tank and its inhabitants.
