Will these work in a mangrove tank? Might be interested. If not what inverts will be good in an mangrove tank?
I'm assuming that the mangrove tank is a brackish tank so you want brackish critters. Olive, crown, and zebra nerites can be good snail wise. Ammanos, ghost, red-nosed, and mandarin shrimp would be good. You may have trouble finding brackish crabs that won't eat everyone though. The micro crabs are full fresh though
Can't waitSomething that I did not find though is an average life span. You have any idea?
Not a clue on that, I figure 1~2 years but I'm not sure
why are they so expensive????
They were expensive to begin with.
