I have noticed that there tends to be a rule of thumb when it comes to the amount of fish recommended for different tank sizes. I am curious what determines that.
Other than the fact that some fish require more room to swim, or that they get a bit large, isn't it mostly how much bio-load your tank can withstand? It seems to me that if the increase is done slow enough, the BB will continue to rise until it reaches a level where there just isn't enough room in the LR
to sustain it any longer. Is that pretty much it in a nut shell?
I am just beginning to stock my 45 Gal
tank. In trying to pick what I want, I am finding that I am very limited (thought it was a big tank until now). Now I understand why everyone wants to up size. LOL Understanding that if my tank is heavily stocked I would, at the very least, have to increase the frequency of PWC
to reduce the rapid increase in Nitrate, I don't really see a big problem. Or, is it that fish just get to feeling crowded and don't do well.
