Oh great to hear everything shuold be fine if I leave it there then...they just kinda disappeared in a few days, wasn't sure if they are hurting the water quality, but I'm just lazy to take it out, also don't want to cause too much drama for my other fishes...also just btw to note here, I love my cleaner shrimp, every time I put my hand in there, the little fella swims after my hand and jump on it to start picking on it...pretty cool...
