Nymphs in my shrimp tanks...

[captmicha]

It's one problem after another... Two of my shrimp tanks have some kind of nymphs in them.

I think this is why my Shrimp have been randomly jumping and I've barely seen any babies.

I did some research, but none of the advice for getting rid of them is reasonable. It'll kill my shrimp or just make the nymphs move around...

These things are like the size of a pin head, they're tiny and I can barely see them. I can't just pick them out from the same color sand and other debris.

This was taken with a macro lens.

Any ideas?

How many nymphs do you see?

I doubt these are doing damage to your shrimp. Shrimp jump when water conditions are bad and/or when they're hungry and/or just because. Cover your tanks better and drop your water level an inch to make it harder.

That said, Nannostomus marginatus or some sort of microrasbora would be ideal for getting rid of those.

At least three. But they're incredibly hard to see.

I was able to remove one and test wormer on it, but it's tolerated it well...

Apparently they're predatory, although I do have a lot of seed shrimp for them to prey on.

I don't understand what you mean by dropping the water an inch to make it harder? GH?

Thanks, I'll look into getting some to help out. Unless you think my pygmy cories would do the same? I could transfer them right over.

Think they are damselfly nymphs? When I search images for water nymph, I get stuff like this:

Seriously, they seem awfully small to be eating adult shrimp. I'd be inclined to wait them out. Let them grow into whatever they become and leave.

The dewormer was a good idea. Too bad it didn't work.

I believe Becca is suggesting lowering the height of the water in the tank. Put it another way, don't fill it to the rim.

Lol. She's welcome to stay as long as she doesn't eat shrimp.

I'm not sure what they are. I thought it was a newly hatched stage of dragonfly, but there are a lot of dob and may and other types of similar flies with similar larval stages, with only minute details to differentiate them. I'm not the best at little details.

Yes, that's what I meant.

In case anyone was wondering, Goat Wormer took care of them!
