i got 3 crabs about a 3 weeks ago. a few days ago i noticed the smell of dead fish. so i took out the shrimp treat i had givin my hermits for the night, and an hour later still smelt dead fish. so i decided to go exploring and locate the smell, i picked up one of the log hidies and their was pincher dead with mites all over her. then i found Jellybean same. so i have mites crawing around in my tank, the mites probably didn't come out when i gave them a bath, which stinks. this coming thursday i will be receiving the predetory bugs i ordered. the third one, Pokey, is doin' fine, nothing is wrong with her or the rest of my crabs.so hopefully i won't lose any more due to mites. oh and my other crab, Melvin wasn't looking good the past few days, i had him for about a month. he lost a leg and the next morning i found him dead in the salt water bowl, he must have slipped and fell and couldn't get out. when i got him from the store he was already missing 2 legs. so i'm really hoping i can get ride of the mites, with the pred. bugs, so i don't have to stress any of the others that are molting and destressing.
