Ok I have a 30 G tank with a 30 gallon filter. I know some1 that's selling a 70 gallon filter for only $20. That's a really good deal I know. But filter is already decent and works ok. Now I have heard that if I have better filtration my tank will be cleaner and clearer (obviously) but also I will be able to add more fish. Now I know I can't add tons more fish or really big fish or anything and I can't have like 30 goldfish in my 30 G (I don't actually have goldfish). I was thinking more like tetras, platys, mollies, danios, maybe a very small loach, MAYBE a catfish, barbs, gouramis, swordtails look cool, rainbow fish, or possibly some killifish. Oh and suggestions for some really cool types to add are welcome too 8) . But like I said would I be able to have more fish with better filtration I'd be at like 100G of filtration for a 30 G tank.
