Fish Fanatic
Thanks for returning the puffer. And I don't know what you guys are thinking of suggesting 3 DPs for a 10G. I've had one almost kill another in a 10G, and that's just with two!
Keep in mind that just because you may have had problems doesn't make the advice wrong.
Keep in mind that my experience has shown that even just two DPs can show too much aggression for that size tank. I was just pointing that out, dude.
That size of tank is too small even for one and I'd recommend you take them both back. They won't be happy or remain healthy in a tank that small! 15 gallons for the first fish, an extra ten gallons for each additional fish (30 gallons minimum for a pair) and heavily filtrated at that!
