I have 4 tetras in my 10g tank, 2 were in there for 3 weeks and 2 more were just added last weekend. At what point do you guys think it would be okay to begin looking at more fish. Also what will do well with my tetras? I was thinking maybe one or two bigger ones or maybe more small fish like the tetras so it will be busy looking. Any suggestions would be appreciated. Also do shrimp add alot to the bioload of a tank and are there any that people particularly like>??? THANKS GUYS!!
