my sons 8g biocube has been cycling for 3 weeks now. has already had the diatom bloom and a cuc added. this morning we found a bunch of these things all over the sand and rock. what are they? good/bad?
my first thought was flatworms (freak out!) but they dont really look like the pics I have seen online. I tried to take some pics closeup. Hopefully they turned out OK.

Pods, copepods, amphipods. Fish food. Love the Dory, just got two in this week.

+1 good for your tank. they eat detritus and algae. They make great food for fish. a good sign that your tank is doing well!!

munnid isopods, harmless.

Just curious, what're you using for substrate? Very uniform (this is the ID forum after all)

It is just a couple bags of the cheapest non-live sand at the lfs. I can find out what kind if you want. my husband is heading there today.

edit~~ The brand is ESTES Its called Ultra Reef Marine Sand..

Thanks, it looks really good
