How do I feed the crabs?
Not sure how long I will feel the need to begin with this disclaimer, but: I'm new at this.
So...I have a 30 gallon tank, with about 20 lbs of live rock. Sadly, Ich has overtaken all of my fish, and they are in a couple of quarantine tanks, where I hope they won't all die. That leaves 2 snails and 2 emerald crabs in my main tank, waiting for a month or so, while the Dreaded Spotty Plague dies off.
Here's my question: How do I feed the crabs?
