I added various crabs and snails to my tank for cleanup purposes last week. I’ve noticed that some of the crabs make their way into my BTA every so often, and when they do, the BTA doesn’t look too happy. However, I’m not sure whether the crabs are harming the BTA or hurting it. Please advise. Thanks!
