2.5 gallons enough for 2 fiddlers?
I have a fiddler crab now in a 2.5 gallon of brackish water, with a sand 'beach' for him to come up on. I have a small snail in there as well to help pick up anything he doesnt eat and to hopefully keep the area clean. I have two questions:
1. Will the snail help keep the tank clean, or should I move it into my other tank?
2. Is the 2.5 tank big enough for one more small fiddler to keep mine company?
