Too much life in my Fallow tank?!?!
 

My fallow tank is in it's 4th week and I was wondering if there is such thing as to many little critters.

Everywhere I look there are big fat pods crawling around everything, there are hundreds of mysid shrimp swimming around out in the open, none of these little guys are even trying to hide anymore.

I even saw a tiny Mantis shrimp hiding in my hairy mushrooms (stomping kind) This one is beige/light brown colored as opposed to my daughter's 1.25" black stomper mantis.

There are so many that I don't have to look close up to see them, is this a problem or will the fish be able to get control once re-introduced?
