Need help taking care of fiddler crabs
 
Hey everyone,

Sorry for not being here in a while even though no one really knows me. My baby mollies are doing extremely well. They are getting bigger and my local pet shop is willing to buy some from me (I've decided to keep 2 females and 1 male.)

I have just recently purchased two fiddler crabs and for some reason the male died shortly after shedding his shell.

They both made repeated trips to the inside of my filter and I had to fish them out....sorry for the pun...:P could that be part of the reason? The female has stayed away from it since....who knows.

Any help would be appreciated thanks!

Midnight

Do you allow acess to air above the water for the crabs?

yes, I had a fake lilly pad (which I have since had to take out and need to replace) but they both preferred to climb up the heater and sit in or on my filter

Quick Edit: I kept the two largest fish which were female and the small 'runt of the litter' which turned out to be female as well so it looks as if I may have to go out and get a male.

The 'runt' , which I've named Gold-Streak due to the one line of gold down one of her sides, may not be growing but eats well and is very active so I'm not that worried about her.

yes they are, SG of 1.005 and access to land, they'll eat fish too.

I would get a piece of driftwood (real or fake) that you could place so it has access to the air. Mine seems to love it and he's always sitting on top. The reason i suggest this is because they seem to take the easiest way to the top and the driftwood works well. Maybe the lilly pad was too difficult for them.

Thanks for that, I'll see what I can find. Right now Jill ( the female crab) has taken to climbing the heater again although now she just sits on the edge of the filter for a few minutes instead of climbing all the way in. Also, the pet store had them in with some other fish and I don't think it was brackish water although I couldn't really tell. I don't know the difference. -winces-

In other news, I went out to buy a couple of angelfish today and came home with a small angelfish and a dwarf frog. Is there anyway to tell the genders of either? I asked the store owner about the angelfish and he said that breeders will generally place a bunch in the same tank and wait until they pair off when they get older.

Bad news. They are brackish. Brackish is basically salt water...just not as much salt as actual salt water (If that makes sense lol).
Unfortunately, I learned this the hard way. The guys at the LPS told me they were freshwater. I said "Are you sure? I'm pretty sure I've read that they are brackish" He says no, they are freshwater. Stupid me, I went ahead and bought one. Sure enough, I get home, research it, and they are indeed brackish. Says that in freshwater, they can survive maximum a few weeks before they become weak and die.

Also, if they don't have easy access to the surface, they tend to crawl up the filter (which I can see has already happened with yours lol). Hope that helps!

Im really glad I saw this thread, I have seen them a few times and really thought about buying some but never knew they were brackish water
