Hello all I need a little advice on my Bio-active terrarium. There is a growing gnat problem in the tank that really needs to be worked on. I have read other threads where people say that the only way to kill them is to bake the soil. However I am hoping for some alternative ideas because aside from the gnats the ecosystem is pretty healthy. The ecosystem includes one six-month old red foot tortoise, ten hermit crabs, earth worms, springtails, a few pill bugs, and live plants planted straight into the soil. This is in a 90gallon terrarium btw. Any who the bio-active terrarium in every other regard is maturing rather nicely and I don't want to have to start over because of the damn gnats. Does anyone have any ideas on living organisms I could add to keep the gnats in check? I don't think I need them completely eradicated just greatly reduced. I was thinking about maybe adding a few poison dart frogs? (The tortoise does eat a earth worm or pill bug every once in awhile but never shows any food interest in the crabs. Plus I assume the frogs could easily outrun the tortoise if he went after them.) Or maybe a pitcher plant? But what if the crabs fall in? I guess I could always find a way to suspend it off the ground. Any advise or suggestions is appreciated. thanks.
