I tested for ammonia and it is barely registering as present. majority of livestock I have is in my 2nd tank, moved this guy over and he doesn't seem to care about being in there so I left him. 3 days and he is happy as a worm. aside from the unsightly algae the tank is stable enough for inverts, I have 6 bumblebee snails, 6 astreas snails, 1 turbo, 1 scarlet hermit crab. everyone is eating and constantly on the move. I'm feeding the tank some pellets and mysis shrimp, the bumblebee snails and hermit eat the shrimps while the pellets is consumed by astreas and turbo.
