Fresh water of sorts

Recommended Posts

Baccus

I have decided to try my hand at hatching and raising some nerite snail eggs. I have set up a small tank with brackish water (the only thing missing for now is crushed coral substrate hope to get some later today), no filter and a light to be left on 24/7 to promote algae growth.

Now my questions are and I hope somebody knows the answers

How long does it take for the dormant eggs to hatch once placed into brackish water?

How big are the newly hatched larva? Seeable with the naked eye or will a microscope or magnifiying glass be needed?

Do they have to be moved into full marine salt or will they develop in the brackish tank?

Does anyone know if each nerite snail egg has only one potential offspring in it or multiple offspring? Because I put probably 20 or so eggs in the brackish tank and am now seeing lots of tiny white dots on the glass but they are beyond my capabilities of getting clear photos of.

Actually there is on very close inspection 3 unknown and all small critters getting about in the tank. 1 type floats about and I have only seen a couple but the look like little yellow orbs.

1 of the other types swims about occasionally and I suspect is a daphnia the other type is again miniscule and moves differently to the suspected daphnia and I am wondering if it could be brine shrimp.

If I move the light on the tank some of the critters will move but not always towards the light, the others seem to stay put on the glass but do move slowly.

No idea @Baccus.

You are breaking new ground here breeding nerites.

However, logic would be to assume one offspring per egg. 

I read this https://primcousa.com/nerite-snail-eggs/ which has a good description of the whole process, but no mention of whether one egg has multiple larvae.

 

Not sure what the other critters could be. Someone with a Marine tank might be able to help.

      Indeed a good video. Except for his spelling of Desolved in TDS (should be Dissolved) I could not have done any better.

      Yes of course! Forgot about high Nitrates, and of course illness. But we probably need to clarify "low temps" for anyone new to the hobby. Winter months can see water temps fall below the shrimp's preferred temp range. It might not be detrimental to their health but it does slow their metabolism down. The remedy for low temps isn't to just give them high temps either, it needs to be within their ideal preferred range for that specific shrimp, eg Neo Caridina or Caridina or Sulawesi. I have known some people to have shrimp (cherries) survive our Australian winter out in ponds. So they can tolerate fairly low temps for an extended period.

      Also No3 , low Temp , and bacteria infections.

      This is a very good video on the basics if you are new to shrimps. It is called 'How to breed shrimp', not sure why as it is generally everything and a very good  and clear video guide?.

      I find the wrong water parameters for the type of shrimp to be a big factor for lethargic shrimp. It's usually the first sign that something is not right. Any measurable amount of Ammonia, can also cause this behaviour.  Moulting is also a big factor in shrimps being inactive. Right before and right after the moult they hide and usually don't move. The moulting process is very strenuous on the shrimp, and I find protein rich foods (eg bloodworms) helps a ton.
