Have My Tetras Spawned?

Not Likely Black Neon Tetras...

Hi,

These should not be I am assuming Hyphessobrycon herbertaxelrodi, Tetra eggs end up on the bottom, they attempt to stick them to plants but the eggs are not all that sticky, they are egg scatterers.

Not sure what they would be.

Get a tub or jar or something and but the eggs and a bunch of aquarium water going, aerate the water, keep it reasonably warm, 75F (24C) and see what turns up. :gw

Step up your green water and infusorians culture. Should they be tetras they will hatch in a day you probably will not see them for 3-5 days.

Agree with Bio.:gw

My Black Neons don't have eggs like that.

 

Just Curious

Hi,

I cannot think what those eggs would be; they really do not look like any of the usual suspect insect eggs.

They rather remind me of “frog spawn” common enough in an outdoor pond I suppose, just unlikely to come hopping through your house in the middle of the night.

I vote for getting a package of those Glad disposable sandwich containers and in addition to the container that is will aerated set up four or six with varying conditions.

That really is curious.

It Is Magic

Hi,

I suppose it could be Anisoptera (dragonflies) or Zygoptera (damselflies), the eggs did not seem familiar, but with 5000 plus species, I suppose…

Dragonflies and damselflies are good guys.

Keep an eye out for little critters in your tank. While eggs of any sort tend to be treated as free Grand-Slam days at Denny’s, some of these eggs hatch very quickly and the larval stages can be very small, taking days or even weeks to reach a size we are likely to notice. They are probably providing your fish with a real treat.

In a tropical tank environment, if any survive, the larval stage could be as little as 60 days that is assuming of course they are or were dragonfly eggs.

• In trying to identify eggs, clear pictures help of course, but noting presents of jelly.
• Is it a single layer or multiple layers?
• How they are laying in the water?
• Are the sticky or slippery?
• When you look at the egg are there any eyes looking back?
• If you can lay or float a millimeter rule along side in the photograph.

Definitely grab at least few in a container. Be aware that if they “disappear” that may just mean they have hatched and are too small for the unaided eye to spot. Just because you cannot see them does not mean they are not hungry.

I love stuff like this…
