I don't know what to think of this at the moment, one of my two fiddler crabs is struggling.. could be hes been sick since i rescued him from wally mart a half week ago.. He's acting very odd if you can't tell from the photos he clearly has no idea which way is up :headshake2:. As of now he's not moving much if at all! Poor guy! Pretty sure its the end of him but i'm putting him in a separate tank just in case he is molting but its not looking good to me.

If this is the end of him, any ideas if i had caused his death? I'm running a brackish tank about 2/3 full with a high approximately 3x5 platform rock for the guys to sit on. I see them up there most of the day. I've tested my water its at a good medium brackish level, tanks at 78 degrees. Any input is appreciated! And i do realize i could use a sloped sandy bottom in this tank but i have a few mollies and would prefer to make a new tank for these guys if i ultimately plan on changing things.

What are your test results showing?
These crabs are very sensitive to ammonia and nitrite, so maybe that is the issue.
I wish your crab the best!

That was it, i tested the ammonia levels, appears as if the change in food and 3 crabs were far too much for the size of the tank, doing partial water changes daily now so here goes nothing!

I noticed you have pebbles in the aquarium, a sandy ground is best for their legs, pebbles are too rough. Before I put sand in my tank my fiddler crab had a pebble stuck in his large claw until he was able to get it out a an hour later.
