HCA: Hermit Crab Association

I have a lot of isopods I’m my tank. It’s 65 gal but there are babies everywhere. Especially when I clean the water pools there in the containers underneath. Is that ok or should I get rid of some?

Well.....I usually agree with with what my fellow mods say, but in this case I don't. If there is a lot of room in the tank, lots of places for them to hide, and lots of food, they will continue to multiply. I personally recommend moving some to a separate container. In one of my crabitats they literally were trying to run the tank. We had a friend come over, and he said, "That's where all of the roly pollies went!" Although the comment was funny, I knew it was time to do something. I started moving them to a tote, and my hermits have been much happier. I wish I could post a video here - It's CRAZY how these guys are multiplying!!!! I have them in a 35 gallon tote, and even though I have layers upon layers of cork bark/oak bark....their number are ENDLESS!

In an aquarium, no matter the size they will simply run out of resources. No matter what, simple ecology. even though our tanks are artificial environments, they simply can not keep multiplying like crazy without consequence.

The consequence was that I started not seeing my hermits as much j/k I just probably didn't let it get that far
