Little bugs
 

I am new to the hobby and have had my tank set up :confused: for about 10 weeks now. When I turned the lights on this morning, I saw thousands of little bugs in the sand. They have now hidden as the lights have been on for a while today. Can you tell me what they are, and is it a concern?

Thanks

I think it is quite common in a newly setup tank. I always get little bugs on the glass. They always disappear in time. :biggrin:

Hopefully they don't completely disappear though! You most likely just had a typical copepod outbreak and you can consider it a good thing :smile:

Yeah they are pods and they come out at night mostly. They are a good thing. If you want to see the nocturnal critters in your tank use a red light, they can't see that. A bunch of things come out at night on the reef :eek:

Bob I'm not sure why they would disappear over time unless they are being predated. :neutral: I've always considered 'pods standard fare in any healthy reef.

I like watching the pods scatter when the lights come on :)
