trying to catch your finger lol. describe them. they are most likely red claw crabs or fiddler( one big claw). either way they need to be able to come out of the water.
they need their own enclosure. most things will eat them. the best tank would be a sand bottom where it is filled a few inches with water and the sand comes out on one side, like a slope. not sure if they need salt. the definetly need sand because they burrow in it.
I've learned that the hard way. I can't remember when it was but we either got frogs or crabs for our aquarium and they climbed up the aerator or filter and got out.
Petsmart had them with fish, no sand and no place to climb out on.
Is it possible for the crabs to get used to a freshwater tank? I have had mine for close to 2 months now, and he seems to be doing fine. He just molted last week. I have some fake grass plant that he climbs up and sits above the water line for a few hours a day. His buddy did escape last week and we found him in the front hall closet The escape hatch has since been closed
