Cockroaches?

[trido]

I keep finding these things in my filter socks when I change them out every month. Anybody know what they are? They look like tiny cockroaches but they are usually alive when I rinse out the filters. I feed my my fish frozen food, so I don’t think I am introducing them to my tank. Any ideas? Are they harmful?

Definitely not pods.

They range in size, the biggest one is about the size of a pencil eraser. I find anywhere between 2 or 3 every time.

Look like water bugs. Except, water bugs are much, much bigger.

Pods get pretty big

I think if they were this size I wouldn’t be pulling them out of the tank, they would probably be pulling me in!

Point being that “pod” is a pretty loose term. That’s not even as big as they come.

I bet they taste like lobster.

I actually was thinking that it was getting into the “good eating” size range. Let us know.

Amphipods, I have had some pretty large ones before.

Those amphipods make great fish food (and food for LPS and anemones)

Never had one. Can you tell me more about them? Correct me if I’m wrong but is it a possibility that they can irritate corals and or fish? Just curious.

Mostly harmless but some types eat corals, those are rare though. They could maybe irritate corals if you had a lot of them. Their numbers are controlled by available food and fish since fish will eat the baby ones, especially wrasses and such. Even shrimp eat them. They are mostly a problem in tiny pico's that don't have any fish.

wow I found smth like this last week in my boat. maybe it is real water bug? Dude, if u have an idea what is this sh*t and how I can kill it, please answer. I showed my friend your pictures and he told me to enter here. I am not sure about it, and it is a reason why I want to know someone else's opinion. I am really scared of bugs even if they are small and don’t bite. But I think bed bugs can give u a lot of problems. Anyways, I hope that you found out what this sea monster is… Pray that no one from us will not meet these bugs… They are really scary. I will read once again the previous’ user comment, maybe I will find smth interesting for myself. Have you ever, guys, met these bugs in your life?? because I have not. And still don't want to meet them lol. Nature sometimes is really terrible... With all these bugs and God's creations..

You probably found an isopod of some sort. There are both freshwater and marine varieties. Do you have any pictures? 

 

"Water bug" is an extremely loose term. If something lives in the water and is a bug, it can be termed a water bug, and people will call anything with an exoskeleton a bug.
