what is this swimming around in my breeder tank???

Hi all -

I keep a 2.5 gallon tank going to breed ramshorn shrimp for my puffers. It works great! I have a steady supply of snails for the puffers and all is well.

Tonight I was setting my bottle trap to catch snails, as I always do, and I noticed some white specks moving around. They are moving in tiny spurts, sort of like daphnia, but now and then one would just sail across the tank! They are really small and I have no idea what they are, but I'm a little nervous about this.

I shot this crappy phone video and you can see them, although the quality is poor. Can anyone throw out an opinion of what these little guys are???

Here's the video!


thanks, Dave

Based on the video, I would say cyclops(copepods) as well.

My roommate says I'll die by giant turtle.

daphnia? I recently had an outbreak of them. The hydra seem to be taking a stab at the population. I can send you some hydra to take care of them.

They don't really swim like daphnia - they are able to make big (but jerky) swims across the whole tank! They are looking like cocopods based on a little youtube browsing.

Are they pretty harmless??

They are attracted to light. My four year old son discovered that.

If you decided to use them as a food source for other fish, that would come in handy for catching them.
