Nano Clown Fish in Calgary

[gobytron]

eventually, war will break out between these two territorial fish and one will die...

it could be in a week or in a year but once one of them establishes itself, theres just no where to hide in a 7 gallon tank.

Also, as far as rinsing food goes, in a tank as small as that, every little bit helps...that being said, you SHOULD be doing enough regular water changes that it really shouldnt matter.
