Too many Fish for my 20 G?

6-8neon Tetras
4Cory Catfish
2 oto catfish
1 Dwarf Gourami
1 angel fish

 

I used to believe that every tank should only have a certain amount of fish according to the size of the tank. As long as your filtration system can handle the bio-load you should be fine.

It would definitely be easier to keep your water crystal clear with less fish. It depends really on your preference. If the fish are the main focus of your hobby then pack them in. I like the ease of having a really clean environment with little maintenance. Plus it seems that my fish have extremely good color comparatively.

 

They'll do fine, not sure why you would add a gourami or angelfish by themselves. Personally, I prefer neon gouramis with the neon tetras.

 

The angelfish should be kept in a larger tank, but to be honest you shouldn't have to worry till he starts getting pretty big.

 

Nope fresh water can handle much more fish per gallon then saltwater

 

The "General" Rule for freshwater is one inch of ADULT fish per gallon, with the correct filtration. In my calc. you are right at it. Should be fine.
