Invasion!

[RaisingKane]

My 130 gallon Ich saga continues. When ich broke out and started taking my fish I did the QT with the remaining survivors and was also advised by my LFS to remove all the sand from my tank. Now in hindsight I am not sure that was the best thing to do but what's done is done. After being fallow for 3 weeks I returned a NEW sand bed to the tank using the controversial "rinse" method to make sure the sand was clean and that there would be minimal disturbance.

Now...I have noticed millions of tiny little white bugs on the glass. I wish I could get a clear video or photo but they are very small. They move so they are not eggs. What the heck are these?

Next I have these longer tiny clear shrimp looking things (photo in the cup). I have read the "What is this thread" so maybe a pod of some type?

And lastly, tiny oval snails. Everywhere. In the sump, on the overflow.

Since going fallow I have been invaded!

Your first image looks like a limpet, https://www.reefcleaners.org/aquarium-store/tank-cleaners/limpets-detail
The second and third images look like amphipods, https://www.fortunaaquatics.com/shop/p/amphipods.

Based on what you're saying, my guess is the tank being fallow has all the little critters fish would normally munch on suddenly booming in population. You're probably fine and once fish are back in the tank their populations will go down. That said the two critters in your images look to be good guys.

So fa it’s a good outcome those are good organisms

OK yes! That second links looks like what is in the cup looked like. It's clear but in the cup you can only see its spine.

And the limpets! That looks pretty close.
The only thing that is really freaking me out are the tiny white bugs all over the glass. I wish I could get a photo or video. My phone will just not focus.

That’s proof that changing out a sandbed, or washing an existing sandbed, does not remove your pod population. They hole up in rock, then come back out. Those bugs were in the old system they weren’t in the bagged sand. They’re quality feed for corals and fish that like to eat them for sure.


fear of losing pods was an original concern in early sand rinse days.

Dig around in the settings. There should be a manual focus option. At least on my phones there is.

If they're "crawling" around like bugs, likely copepods, also good,,, but just guessing

My vote is also copepods. Look almost like white spots crawling all over the glass

Thank you everyone! I assumed that this was all the life coming out into the world now that there are no fish to eat them but wasn't sure. Seemed coincidental but things just keep happening right and left! A few more weeks of copper and then the fish will be back and the shrimp and hermits and everything else ruling this tank right now (which I typically only see at night) will be running for the rocks again.

Crazy how many bugs and organisms are in there.

It is, from my own experience running a tank fallow had the pod and other similar critter populations skyrocket. When the fish were back they feasted.
