I have a 70 litre tank with 8 black phantom tetras and 4 dwarf gouramis in it. I was told that the maximum amount of fish that can be kept in a tank depends on the filtration capabilities. I currently have an interpet PF2 internal filter that is suitable for 45-90 litre tanks. If my tank is currently fully stocked, would adding a second filter, perhaps one which hangs on the back, allow me to add a few more fish.
All i wanted to add were some cardinal tetras, but i don't want to add them if it is not fair on the fish, or likely to cause an ammonia crash.
If i am being stupid here please tell me. Thanks.
