I keep seeing these little tiny fish darting around in the caves of my liverock. They are barely visible to the naked eye, are semi-clear and have big eyes. I'd say about 1-1.5 mm in length. What are they? Are they bad? Please advise. The 12G tank is about 2 months old, and has liverock/livesand, Crabs, Snails, a Blenny, and 2 Perculas.

Thanks!

Sounds more like a pod variety and will be beneficial to your tank! These organisms act as food for just about any fish.

They are pods (copods and amphiods). Try looking at your tank with a flashlight a couple hours after the lights go out and you'll probably see a ton more than you see when the lights are on.

Interesting... Thank you!

I have tiny little fish like that and they are not 'pods.. i'm wondering if they'll get big?? (if my fish don't eat 'em!) does anyone else have baby fish under their live rock?? and do you know what they might be?

do they look like this?

[cjfreitas]

no, there more like tiny clear tetras.. they look like they have a little bit of a blue line across them..
